Heavy accent and not very tech savvy. Tackling truly hard questions in number theory leading to the first finite bound on a gap between prime numbers and the best possible qualitative approximation of the twin prime conjecture. Also, he announces what the quiz will cover in the lecture. He has a strong Chinese accent though I think it's ok for me. "Right now the best bound on gaps between primes is 270," he told Crave, "although we Zhang, Yitang [Zhang, Yi Tang] (1-NH-NDM) Bounded gaps between primes. Das System kann den Vorgang jetzt nicht ausfhren. Y Zhang, Y Cheng, W Jiang, Y Ye, Q Lu, H Zhao. Fortunately, lectures are recorded and his notes are exceedingly clear. Proceedings of the National Academy of Sciences 111 (32), 11612-11617. [5][6][7][8], Zhang was born in Shanghai, China, with his ancestral home in Pinghu, Zhejiang. Yitang lived in his car, worked at Subway for sometime (as an accountant) and finally (7 years after his PhD) was hired as a lecturer at a small university (1999). Additionally, he will intentionally ignore your emails, if he does not understand questions you ask him. Beware what TA you get because the TA this quarter was ridiculous and graded super harshly. Prime numbers have inspired great intrigue over the last centuries, and one of the most basic unanswered questions has been the spacing between two consecutive prime numbers, or the twin prime conjecture, which states that there are infinitely many pairs of primes that differ by two. Blessings from Shaoxing, China. Zhang himself says that "something impressive" probably has no practical application, though prime numbers do extend beyond the realm of pure math into more real-world uses. Midterms and Finals are extremely reasonable and fair considering how much prep material he releases. Become a home entertainment expert with our handpicked tips, reviews and deals. February 1, 2015.

Technology dumb, had him for online class, and his lectures were horrendous because he simply did not know how to work the online classes. 15. ", In addition, he said, Zhang's proof came as something of a shock to the number theory community. The second phase of Polymath8, called Polymath8b, builds on Maynard's work. Stability analysis and variable speed limit control of a traffic flow model. They developed a "sieve" to filter for pairs of primes that are closer together than average, as did Zhang. Homework was half computational and half proofs but the graded problems were lenient. The ones marked, Journal of Applied Crystallography 48 (3), 917-926. He is an amazing and understanding teacher. The homework can be rather difficult, but he gives many hints. Good lectures but can be boring because he talks slow and quietly and he writes on a chalkboard. 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. 4. In his paper, Zhang obtained for the first time an unconditional advance on : Theorem 6 (Zhang) is true for all . Also, my advisor [Tzuong-Tsieng Moh] did not write me letters of recommendation. The privacy of your data is important to us. 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 ", Polymath 8 has been one of the most active, visible Polymath projects to date, and Tao attributes the excitement surrounding it, in part, to Zhang's compelling personal story -- after suffering the hardships of the Cultural Revolution, Zhang earned a bachelor's and a master's degree from Peking University, and completed a doctorate from Purdue, but had difficulty obtaining a university job in the US.

Dr. Zhang was a recipient of the 2014 MacArthur Award, and was elected as a Fellow of If P(N) stands for the proposition that there is an infinitude of pairs of prime numbers (not necessarily consecutive primes) that differ by exactly N, then Zhang's result is equivalent to the statement that there exists at least one even integer k < 70,000,000 such that P(k) is true. [9] He served as lecturer at UNH from 1999[15] until around January 2014, when UNH appointed him to a full professorship as a result of his breakthrough on prime numbers. The good news is that he gives really easy exams. The system can't perform the operation now. 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). That was a job market problem. This is a deep result, building upon the work of Fouvry-Iwaniec, Friedlander He worked as a laborer for 10 years and was unable to attend high school. [9] During the Cultural Revolution, he and his mother were sent to the countryside to work in the fields. Yitang Zhang: A prime-number proof and a world of persistence. [21] Subsequently, in April 2014, the Polymath project 8 lowered the bound to k 246. This is a story about prime numbers and the man who took a giant step toward solving a puzzle that has vexed mathematicians for centuries. Yitang Zhang (Chinese: ; born February 5, 1955) is a Chinese American mathematician primarily working on number theory and a professor of mathematics at the University of California, Santa Barbara since 2015. 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.

Zhangs work shows that there are infinitely many consecutive primes, or pairs of primes, closer than 70 million. Go to lectures and take notes and you'll pass. ", Zhang himself, a self-described "shy person," said in a UNH statement that the proof came to him during a vacation in Colorado, when he was feeling particularly relaxed. Beijing University of Posts and Telecommunications. 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 To my surprise, Prof Zhao said: Yitang was not a student of Prof Ding, Yitang was a student in number theory under Prof Pan. When his paper got accepted, Zhang said he expected the formulas contained therein to form the basis for narrowing the 70 million gap. Highly recommend. 86 on the final, 78 on the midterm, 100 on the homework, but a 67% on the quizes due to them being at 8am and missing two. 25. Dr. Yitang Zhang. On May 9, mathematician .
