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. In a 2013 interview with Nautilus magazine, Zhang said he did not get a job after graduation. I overslept for midterm but he's so nice and allowed me to take make-up midterm. Minding the gap Really recommend him! Practice exams are exactly like midterms and finals, with numbers and variables changed. This "Cited by" count includes citations to the following articles in Scholar. That man, Yitang "Tom" Zhang, was exiled to the Chinese countryside during Mao's Cultural Revolution as a teen and forced to quit his studies and perform hard labor. Y Zhang, Y Cheng, W Jiang, Y Ye, Q Lu, H Zhao. This work led to a 2013 Ostrowski Prize, a 2014 Cole Prize, a 2014 Rolf Schock Prize, and a 2014 MacArthur Fellowship. [9] He first learned about Fermat's Last Theorem and the Goldbach conjecture when he was 10.

Yitang Zhang Let rho' = beta' + i gamma' denote the zeros of zeta' (s), s = sigma + it. Tests were fair, really fair. Fortunately, lectures are recorded and his notes are exceedingly clear. Definitely take him, helps you understand and is an easy grader. However attending classes would give basic ideas about materials in homework and exams. semester, Prof Zhao and Yitang greeted to each other. The system can't perform the operation now. Stability analysis and variable speed limit control of a traffic flow model. 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. Yitang Zhang (Chinese: ; born February 5, 1955)[3] is a Chinese American mathematician primarily working on number theory and a professor of mathematics at the University of California, Santa Barbara since 2015. And suddenly it came to me. 5 minue 8am section grades (6 of them) account for 35% of the grade. [21] Subsequently, in April 2014, the Polymath project 8 lowered the bound to k 246. And they have. Try again later. ", In addition, he said, Zhang's proof came as something of a shock to the number theory community. Midterms and Finals are extremely reasonable and fair considering how much prep material he releases. Yitang Zhang at the University of California, Santa Barbara (UCSB) in Santa Barbara, California has taught: MATH 108B - Introduction to Linear Algebra, MATH 115A - Introduction to Number Theory, MATH 108A - Introduction to Linear Algebra, MATH 115B - Introduction to Number Theory, MATH 260HH - Seminars in Mathematics, MATH 225A - Topics in Number Theory, In November, James Maynard, a postdoctoral researcher at the University of Montreal, presented independent work that built on Zhang's to further shrink the gap -- to 600. "During that period it was difficult to find a job in academics. C. Gauchospace is empty so there's no syllabus to refer to. 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]. , 2021. An exciting breakthrough by an academic little known before last year is firing up mathematicians. [7] In 2018, responding to reports of his treatment of Zhang, Moh posted an update on his website. In a 2013 interview, he affirmed that his political views on the subject had not changed since. The system can't perform the operation now. He lived in Shanghai with his grandmother until he went to Peking University. This award is used to honour persons who serve as role models and a source of inspiration for Asian American engineers and scientists. [7] Zhang's result set off a flurry of activity in the field, such as the Polymath8 project. ", 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. 15. i10-index. His work has generated significant collaborations across the community to expand on his effort, and within months of his discovery that number was reduced from 70 million to less than 5,000. Committed to building a more just, verdant, and peaceful world, 2023 John D. and Catherine T. MacArthur Foundation. Environmental Previous studies have demonstrated that metabolic disorders are prone to diabetic encephalopathy and atherosclerosis ( Barenbrock et al., 1995 ), which will generate Alzheimers disease and coronary heart disease ( Razay et al., 2007 ). Chemical Engineering Journal 302, 526-534. , 2016. After graduation, Zhang had trouble finding an academic position. The homework can be rather difficult, but he gives many hints. His work has sparked a frenzy among mathematicians the world over, who have collaborated through the online Polymath project to further hone his proof. When she's not smithing words, she's probably playing online word games, tending to her garden or referring to herself in the third person. Transportation Research Part B: Methodological 118, 31-65. , 2018. [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]. What he talks about in lecture barely has nothing to do with what appears in homework and exams. The classical form of the twin prime conjecture is equivalent to P(2); and in fact it has been conjectured that P(k) holds for all even integers k.[19][20] While these stronger conjectures remain unproven, a result due to James Maynard in November 2013, employing a different technique, showed that P(k) holds for some k 600. Try again later. So I often feel confused in his class. Grigori Perelman (solved the Poincar conjecture): h-index 10. San Francisco Bay Area playwrights belonging to SF PlayGround, which develops new theatrical works, recently attended a lecture on Zhang at the MSRI. The second phase of Polymath8, called Polymath8b, builds on Maynard's work. The ones marked * may be different from the article in the profile. Beware what TA you get because the TA this quarter was ridiculous and graded super harshly. At around the age of nine, he found a proof of the Pythagorean theorem. Their combined citations are counted only for the first article. Yitang Zhang: A prime-number proof and a world of persistence. ", 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. Good lectures but can be boring because he talks slow and quietly and he writes on a chalkboard. Additionally, he will intentionally ignore your emails, if he does not understand questions you ask him. The exams were super easy though. 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. 133. The following articles are merged in Scholar. Zhang was awarded the 2013 Morningside Special Achievement Award in Mathematics,[23] the 2013 Ostrowski Prize,[24] the 2014 Frank Nelson Cole Prize in Number Theory,[16][25] and the 2014 Rolf Schock Prize[26] in Mathematics.

Terence Tao, a UCLA professor of mathematics and winner of the esteemed Fields Medal, launched Polymath8 as a forum where mathematicians could work to reduce that gap between 70 million and 2, which they did to 4,680 within a few months of Zhang submitting his paper. He is a recipient of the 2014 MacArthur award,[27] and was elected as an Academia Sinica Fellow during the same year. [4], Previously working at the University of New Hampshire as a lecturer, Zhang submitted a paper to the Annals of Mathematics in 2013 which established the first finite bound on the least gap between consecutive primes that is attained infinitely often. Prior to getting back to academia, he worked for several years as an accountant and a delivery worker for a New York City restaurant. 3, 1121{1174.
