I remark to Prof Zhao that Mr Zhang was a student of me and casually mentioned that Yitang was a student of Prof Ding (an algebraist). While these conjectures have no known direct applications, although some allude to possible impact in cryptography, they represent a quintessentially hard problem, an area that has frustrated generations of mathematicians. "During that period it was difficult to find a job in academics. Committed to building a more just, verdant, and peaceful world, 2023 John D. and Catherine T. MacArthur Foundation. Tao also credits the relative simplicity of the result, "which can be explained to any decent high-school math student (unlike many recent advances in mathematics). Everyone should take his MATH 6A for letter graded. Environmental 2021. He worked as a laborer for 10 years and was unable to attend high school. (For a highly detailed but clear explanation of Zhang's approach and results, read this Quanta Magazine article by Erica Klarreich). Historically, much of the progress in sieve methods has been driven by the Twin Prime Conjecture, which states that there are in nitely many primes psuch that p+2 is also prime. Yitang Zhang's opinion may be quoted at here: The passage may be translated as: Yitang Zhang: He believed he was correct, and Yitang Zhang received a B.S. 110 (3) 555 - 572, 1 December 2001. https://doi.org/10.1215/S0012-7094-01-11034-X Information Published: 1 December 2001 First available in Project Euclid: 18 June 2004 zbMATH: 1012.11081 MathSciNet: MR1869116 In 1989 Zhang joined a group interested in Chinese democracy (). So I often feel confused in his class. The ones marked * may be different from the article in the profile. "[12] Zhang made this claim again in George Csicsery's documentary film "Counting from Infinity: Yitang Zhang and the Twin Prime Conjecture"[13] while discussing his difficulties at Purdue and in the years that followed. 2015. Y Zhang, Q Lu, Y Ye, K Huang, W Liu, Y Wu, X Zhong, B Li, Z Yu, Y Zhang, Y Cheng, W Jiang, Y Ye, Q Lu, H Zhao, Briefings in bioinformatics 22 (5), bbaa442. After graduation, Zhang had trouble finding an academic position. His seminal work was published in the Annals of Mathematics.

Homework also helped a lot if u do want a decent grade, and the workload is fine. of Math. [22] With current methods k 6 is the best attainable, and in fact k 12 and k 6 follow using current methods if the ElliottHalberstam conjecture and its generalization, respectively, hold.[7][22]. Their, This "Cited by" count includes citations to the following articles in Scholar. Physical Chemistry Chemical Physics 15 (18), 6567-6582. Y Zhang, Y Cheng, W Jiang, Y Ye, Q Lu, H Zhao. Zhang became a professor of mathematics at the University of California, Santa Barbara in fall 2015. The Institute Letter Summer 2014. While 70 million is a long, long way away from 2, Zhang's work marked the first time anyone was able to assign any specific proven number to the gaps between primes. Transportation Research Part B: Methodological 118, 31-65. , 2018. [9] Moh claimed that Zhang never came back to him requesting recommendation letters. Fortunately, lectures are recorded and his notes are exceedingly clear. After the Cultural Revolution ended, Zhang entered Peking University in 1978 as an undergraduate student and received a bachelor of science in mathematics in 1982. He became a graduate student of Professor Pan Chengbiao, a number theorist at Peking University, and obtained a master of science in mathematics in 1984. [10] "Fifty years ago no one would have dreamed that anything about primes had a practical application, and large, secret primes are now the basis of some of the cryptography that makes Internet commerce possible," David Eisenbud, former head of the Mathematical Sciences Research Institute (MSRI) in Berkeley, Calif., told Crave. "And now we've got somebody who's literally come of nowhere, that no one expected to produce this kind of results, and has done something impressive that many great minds were unable to do.". Despite his accent, Professor Zhang was able to explain things very clearly, which helped grasping the essence of abstract concepts. [21] Subsequently, in April 2014, the Polymath project 8 lowered the bound to k 246. Verified email at mail.tsinghua.edu.cn. Yitang Zhang is a mathematician who emerged from relative obscurity with a landmark achievement in analytic number theory: the so-called bounded prime gap, which essentially establishes that the difference in spacing between two consecutive prime numbers is, infinitely often, bounded by a fixed number. Midterms and Finals are extremely reasonable and fair considering how much prep material he releases. [7] In 2018, responding to reports of his treatment of Zhang, Moh posted an update on his website. That phase of the project was Polymath8a. Later in San Francisco Bay Area playwrights belonging to SF PlayGround, which develops new theatrical works, recently attended a lecture on Zhang at the MSRI. He is an amazing and understanding teacher. Quoting Du Fu's poem again Amazing mind and equally amazing professor. Beijing University of Posts and Telecommunications. Leslie Katz leads a team that explores the intersection of tech and culture, plus all manner of awe-inspiring science, from space to AI and archaeology. [9] During the Cultural Revolution, he and his mother were sent to the countryside to work in the fields. There is no curve because his tests are so easy.

"Right now the best bound on gaps between primes is 270," he told Crave, "although we Sign up for periodic news updates and event invitations. (1982) and M.S. The system can't perform the operation now. 133. Yitang Zhang has (apparently) claimed that he's solved the Landau-Siegel Zeros Conjecture I don't see any sources in English yet, but here's a Chinese source ( https://mp.weixin.qq.com/s/H5Sr4jWEo2q52fiCgC9N3w) writing that Yitang Zhang mentioned he's solved the Landau-Siegel Zero conjecture in a talk given to the Peking University Alumni Home Institution University of New Hampshire. The system can't perform the operation now. Dr. Yitang Zhang. Das System kann den Vorgang jetzt nicht ausfhren. Later, after receiving advanced degrees in China and the US, he struggled to find an academic position and at one point worked behind the counter at a Subway sandwich shop. The best Professor in UCSB! 25. The following articles are merged in Scholar. Respectful professor. Despite his accent, Professor Zhang was able to explain things very clearly, which helped grasping the essence of abstract concepts. Besides, he gave practice exams that are very similar to the actual exams, so be sure to understand how to solve them.
