Liu Kefeng's growing experience.

Liu Kefeng,/kloc-0 was born in February 1965,/kloc-0 graduated from Peking University in 1985, and/kloc-0 received a doctorate in mathematics from Harvard University in 1993. In 2000, he was an associate professor in the Department of Mathematics at UCLA, and in 2002, he was a professor in the Department of Mathematics. In 2003, he served as the executive director and dean of the Department of Mathematics of Zhejiang University, and was the first batch of cursor professors. Editor-in-Chief of Analysis and Geometry Communication.

Liu Kefeng, a professor at UCLA, a cursor professor at Zhejiang University and the executive director of the Mathematics Center, is a world-famous young master of mathematics.

He proved the marino-Wafa conjecture, the "mirror image conjecture" in superstring, the Qiu Chengtong metric equivalence conjecture in differential geometry and the famous Witten rigidity theorem in topological quantum field theory.

He dabbled in many different fields of mathematics, and always grasped the most important problem in this field, gave simple but extremely exquisite proofs, and made a lot of world-class original innovations in differential geometry, topology, mathematical physics and other directions.

In 2004, at the Third International Congress of Chinese Mathematicians held in Hongkong, Liu Kefeng was awarded the highest prize in Chinese mathematics-Morningside Mathematics Gold Award. In addition, he has won many awards, such as Harmo Award, Sloan Award and Terman Award.

A student in Liu Kefeng said, "Whenever Mr. Liu has a class, the classroom is always full. His humorous language and profound and wise thoughts always show the essence behind boring concepts to the audience. As soon as he began to speak, all eyes were attracted by him. In the eyes of ordinary people, abstruse mathematics and old-fashioned mathematics are as fascinating as Zhang Hui's novels. " Liu Kefeng, male, 1965, a native of Henan. He was a famous troublemaker in school when he was a child. Because my father changed jobs and became a soldier in Tianjin, he studied in Tianjin. Young Liu Kefeng can't see the shadow of a talented mathematician. He is stubborn and naughty, and climbing trees is a common practice.

At first, Liu Kefeng's grades were mediocre. In the third year, the situation changed dramatically, because a beautiful girl came to the class, and her appearance made Liu Kefeng feel the inner shock. This girl is not only beautiful, but also has excellent grades. She was the first in her class in the first exam.

Liu Kefeng fell in love with this girl at first sight, and his admiration for her grew deeper and deeper. He began to think secretly about how to win the girl's heart. He found that girls like to associate with studious students. There is a door! From then on, he changed his previous carelessness, studied hard, and his grades soared, especially in mathematics, winning prizes frequently in various competitions. In the end, his excellent performance was not in vain. Ganoderma lucidum was extremely proud to finally board the palace and win the laurel.

I don't want to kill two birds with one stone Liu Kefeng accidentally found himself in love with a "lover" while embracing the beauty's heart, and stayed with him all his life. He often got up in the middle of the night on a whim and savored it.

This "lover" is math.

198 1, admitted to the Department of Mathematics of Peking University. Four years later, Liu Kefeng was admitted to the Institute of Mathematics of China Academy of Sciences. From then on, he embraced a beautiful woman and became a "lover", wandering between material beauty and spiritual beauty. He embarked on one problem after another, singing all the way in the field of mathematics and heading for the commanding heights of life.

Another mathematician lamented: "There are two beautiful women, and this life is enough." 1in the summer of 985, Liu Kefeng, who just graduated from university and was admitted to graduate school, attended the National Summer Mathematics Class for Postgraduates held by Chen Shengshen at Nankai University and got to know the world's top geometer Chen Shengshen.

Chen Shengshen's achievement is called "Chen Lei" in mathematics, which has brought differential geometry into a new era and influenced the development of mathematics and modern theoretical physics.

Listening to the master's academic lecture for the first time, Chen Shengshen attracted Liu Kefeng like a charming smile magnet.

Chen Shengshen personally designated the summer school textbook-American mathematician Porter's Lecture Notes on Topology. For Liu Kefeng who just graduated, this book is awkward and difficult to understand, just like a gobbledygook. Fortunately, he has perseverance and toughness. He believes that the teaching materials designated by the master must be good things, so he chews them repeatedly even if he doesn't understand them.

Gradually, Liu Kefeng fell in love with this textbook. Liu Kefeng recalled: "1On a hot summer day in July, 1986, I lay in a daze on a summer mat, but my mind was full of ideas about how to localize. Suddenly, my confused thoughts suddenly became clear, and a carp sat up and excitedly flashed a key step in his mind-Porter's formula is the answer to the question! "

"That moment can be said to be the most exciting moment in my research career. The idea at that moment gave me the first paper in my life and also gave me confidence to become a mathematician. "

On a cold morning, after playing all night, Liu Kefeng curled up in bed and was awakened by a quick knock at the door. The ticket holder is Wang Qiming, deputy director of the Institute of Mathematics of China Academy of Sciences. Professor Wang's enthusiasm immediately eliminated his laziness. It turns out that when Wang Qiming saw his paper, he found its novelty and subtlety, so he came to see you in person.

"You have a good foundation and should go abroad for further study." Wang Qiming said. 1988 At the beginning of this year, Liu Kefeng, who was just married and immersed in happiness, suddenly received a doctoral application form from the Department of Mathematics of Harvard University. The sender is actually Qiu Chengtong, a master of mathematics.

At the age of 27, Qiu Chengtong solved Calabi's conjecture, a difficult problem in world mathematics, and at the age of 33, he won the Fields Prize, the highest prize in world mathematics. It was Wang Qiming who sent Liu Kefeng's paper to Qiu Chengtong. Qiu Chengtong fell in love with Liu Kefeng at first sight, and his love for talents was sudden and was taken into his family.

Liu Kefeng joy inexplicable, a few doubt in a dream. 1September, 988, Liu Kefeng came to Harvard and became a disciple of Qiu Chengtong.

At Harvard, Liu Kefeng met the "bad" Potter. In life, Potter never "twists and turns". When Porter's residue theorem was combined with this straight-backed, unhurried porter on Harvard campus, Liu Kefeng's excitement could be imagined. Potter is his dream. It was this dream that brought him to Harvard, and now this dream extends to his future.

Porter liked this handsome, intelligent and talented China boy from the beginning.

Witten, a legend in physics and mathematics, focused on history in college and turned to physics in graduate school. Later, due to Porter's guidance, he also made extraordinary achievements in mathematics and won the Fields Prize, the highest prize in mathematics. In 1980s, he put forward a famous conjecture-Witten's rigidity theorem. The conjecture put forward by the students was proved by Bao Te, a teacher, and another mathematician, Tao Bushi, but the proof was so complicated that almost no mathematician could understand their proof.

Liu Kefeng, a fearless young man, openly proposed to find a new way to simplify the proof of the teacher's teacher Porter. A few months later, he gave an extremely exquisite proof, thoroughly expounded the difficulties in this field, and applied the modular form to the study of topology and geometry for the first time, opening up a new research direction.

"After the proof, no one believes that my proof is correct. I talk to Potter once a week to explain my proof. " Liu Kefeng said, "Porter invited me to talk about my achievements at his seminar. Many great professors came to the first seminar. Later, a great mathematician told me that I was talking about a very sensitive topic that others dared not talk about. " At that time, many mathematicians doubted the correctness of the rigidity theorem.

Liu Kefeng really succeeded! He not only made a great breakthrough in the understanding of Witten's rigidity theorem just proved by Porter and Taubusch, but also gave an extremely concise and "very beautiful" proof, and also deduced several brand-new rigidity and extinction theorems, and found an unexpected and profound connection with other branches of mathematics. Porter was more excited than Liu Kefeng. He rushed to Paris to give a speech on Liu Kefeng's latest achievements.

Many years later, Potter wrote emotionally in the introduction of his complete works: "Liu proved Witten's rigidity theorem very concisely and found a brand-new rigidity theorem and its unexpected connection with infinite dimensional Lie algebra. I am very happy to see that my beloved attiya-Porter fixed point theorem still plays an important role here. "

1993, Dr. Liu Kefeng graduated. At this time, he has been widely recognized in American mathematics, and universities have invited him to work. He has taught at MIT, Stanford University and UCLA.

Liu Kefeng's career has entered a period of high production. The conquest of the mirror symmetry conjecture won him the Guggenheim Hammer Award, which is one of the highest awards given to American scientists, artists and writers who have made great achievements.

Since 1994, Liu Kefeng has presided over and undertaken important scientific research projects such as the National Science Foundation of the United States, and won the Sloan Award and the Terman Award. At this time, Liu Kefeng has become one of the first-class mathematicians in the world, and his academic status has been recognized by his peers.

In 2000, he came to UCLA. This is where the tutor Qiu Chengtong proved Calabi's conjecture, and where many famous mathematicians proved their famous theorems. As soon as Liu Kefeng arrived here, a more amazing world problem immediately entered his field of vision-marino-Wafa conjecture. Together with, he proved the famous geometric equivalence conjecture put forward by Qiu himself more than 20 years ago. Internationally, all three of them are named after the new gauge introduced in their certificates: Liu Sunqiu Gauge. In August 2002, the newly-built Yongqian Mathematics Building of Zhejiang University attracted the attention of the whole world. The string theory meeting of the International Congress of Mathematicians was held here. The "Gemini" in the international physics field-"Newton" Witten and "Einstein in a wheelchair" Hawking gathered in Hangzhou, and Nobel Prize winner Gross and others attended the meeting. The organizers of this activity are Qiu Chengtong and Liu Kefeng.

With the direct efforts of Qiu Chengtong, after nearly two years of brewing, the Mathematics Center of Zhejiang University was established. However, after the establishment of the center, there is a lack of a leading figure who can lead the world mathematics trend. Qiu Chengtong thought of Liu Kefeng.

At that time, Liu Kefeng was at the peak of his life and career. In 2002, he won Gu Geng's Hamo Prize, and therefore won a rare award-a year off from school. Before he could arrange this year's work, the teacher called his home: "Can you go to the Mathematics Center of Zhejiang University to preside over the work?"

In June, 2003, China was shrouded in the shadow of SARS, but Liu Kefeng flew to Hangzhou, where he was employed as the executive director of the Mathematics Center of Zhejiang University and concurrently the head of the Department of Mathematics.

After Liu Kefeng took office, the center operated in full accordance with international practice, implemented a professor system, and established academic, teaching and logistics committees to give front-line professors autonomy; Publish the latest academic achievements online, implement the online office system, and advocate the communication between professors and students online. As soon as this move came out, the mathematics departments of various schools all over the country followed suit and proposed to cancel the requirement that master students must publish papers and implement a reading report system to prevent master students from falsifying their papers.

In order to cultivate top talents, Liu Kefeng is determined to start from the foundation, set up Qiu Chengtong Mathematics Talents Class, recruit talents from all over the world, and personally select talents in middle schools.

How to attract high-level mathematicians to the center for teaching and research? Liu Kefeng has his own brilliant idea: to attract celebrities by holding top international academic activities. In the past three years, the Mathematics Center of Zhejiang University has held more than 30 major events, which attracted a large number of world-class masters to exchange lectures here: Witten, winner of Fields Prize, Hawking, winner of Turing Prize, Gross and Hofter, Yao Qizhi, academicians of European and American National Academies Coates, Bohr, Hall, Xiao Gai, Bo Guinong, Hamilton, Cafarelli and Luttieg. ...

The center has introduced a large number of top talents and established a world-class academic team. There are 4 professors in Guangbiao, 30 professors in Changjiang/KLOC-0 and 30 senior professors in Mathematics Center.

In just three years, the mathematics discipline of Zhejiang University has soared to the top in the country. The enrollment ranking of mathematics department of Zhejiang University jumped from the fifth in the whole school to the top two. After arriving at Zhejiang University, Liu Kefeng still achieved a lot. His marino-Wafa conjecture proved to be one of the top ten scientific and technological advances in China universities in 2004. Qiu and Liu jointly proved Qiu's world-famous geometric metric equivalence conjecture put forward more than 20 years ago, and Zhang Yi, a postdoctoral fellow at the Mathematics Center of Zhejiang University, made an important breakthrough in the study of Calabi-Qiu rigidity. These three landmark achievements were published by the top international publications Journal of the American Mathematical Society and Journal of Differential Geometry, and were highly praised by international academic circles.

Liu Kefeng feels more and more that mathematics is so simple and beautiful, simple and gorgeous, like the light makeup of Xizi Lake, so beautiful that no words can express it. At the Third World Congress of Chinese Mathematicians, Liu Kefeng won the highest prize, the "Morningside Mathematics Gold Award". In the face of media reporters, he confessed his love for mathematics: "If there is an afterlife, I will still be a mathematician!" "
