Y Zhang, XB Li, AM Fleming, J Dood, AA Beckstead, AM Orendt, Journal of the American Chemical Society 38 (23), 73957401. 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. San Francisco Bay Area playwrights belonging to SF PlayGround, which develops new theatrical works, recently attended a lecture on Zhang at the MSRI. ", In addition, he said, Zhang's proof came as something of a shock to the number theory community. Dr. Zhang was a recipient of the 2014 MacArthur Award, and was elected as a Fellow of By Guy Spriggs. Try again later. 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. The system can't perform the operation now. Zhang became a professor of mathematics at the University of California, Santa Barbara in fall 2015. 25.

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, 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 J. The homework can be rather difficult, but he gives many hints. Zhangs work shows that there are infinitely many consecutive primes, or pairs of primes, closer than 70 million. "[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. His work has sparked a frenzy among mathematicians the world over, who have collaborated through the online Polymath project to further hone his proof. In 1999, 8 years after he had finished his Ph.D., Dr. Zhang found a teaching position as a lecturer in University of New Hampshire. The good news is that he gives really easy exams.

Recently named a professor in the Department of Mathematics at the University of New Hampshire, he worked in a wide array of positions, including as an accountant and a delivery worker, before joining the faculty of the University of New Hampshire as a lecturer in 1999. They developed a "sieve" to filter for pairs of primes that are closer together than average, as did Zhang. 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. He also worked in a motel in Kentucky and in a Subway sandwich shop. "Right now the best bound on gaps between primes is 270," he told Crave, "although we This work led to a 2013 Ostrowski Prize, a 2014 Cole Prize, a 2014 Rolf Schock Prize, and a 2014 MacArthur Fellowship. "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. Zhangs impact will surely grow as he turns his focus and incredible perseverance to other truly hard questions in number theory. He is an amazing and understanding teacher. Department of Mathematics South Hall, Room 6607 University of California Santa Barbara, CA 93106-3080. His seminal work was published in the Annals of Mathematics. His explanations simplify things HEAVILY. [10] He was an invited speaker at the 2014 International Congress of Mathematicians. The system can't perform the operation now. After receiving his master's degree in mathematics, with recommendations from Professor Ding Shisun, the President of Peking University, and Professor Deng Donggao, Chair of the university's Math Department,[11] Zhang was granted a full scholarship at Purdue University. So was the homework. 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.

[5][6][7][8], Zhang was born in Shanghai, China, with his ancestral home in Pinghu, Zhejiang. The ones marked, Journal of Applied Crystallography 48 (3), 917-926. Heavy accent and not very tech savvy. The talk served as an inspiration for original math-themed short plays, some of which will be performed Monday night at the Berkeley Repertory Theater in Berkeley, Calif., at a program titled "A Passion for Primes.". When his paper got accepted, Zhang said he expected the formulas contained therein to form the basis for narrowing the 70 million gap. 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. In his paper, titled "Bounded gaps between primes" and bearing his name alone, Zhang attacked the problem by proving that the number of primes that are less than 70 million units apart is infinite. The conjecture holds that there is an infinite number of prime numbers (numbers divisible only by 1 and themselves) that are only two numbers apart -- like 3 and 5 or 17 and 19. 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. 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. Homework also helped a lot if u do want a decent grade, and the workload is fine. He can look intimidating but is very very nice. Fax (805) 893-2385 Bounded Gaps Between Primes by Yitang Zhang, an adjunct professor at the University of New Hampshire, immediately caught the attention of the editors Yitang Zhang (, born 1955) was born in China and is now a professor of mathematics at the University of California. Fax (805) 893-2385 Email: www@math.ucsb.edu Office Hours: Mon-Fri 9-12, 1-4 [18] The proof was refereed by leading experts in analytic number theory. Despite many efforts at proving this conjecture, mathematicians were not able to rule out the possibility that the gaps between primes continue to expand, eventually exceeding any particular bound. Sit in the front because his handwriting is small and his voice is soft. The midterm and final are extremely faithful to the practice versions, and mostly computation-based. This result implies the existence of an infinitely repeatable prime 2-tuple,[1] thus establishing a theorem akin to the twin prime conjecture. After a years-long hiatus, Zhang published his Landau-Siegel Zeros paper today. On April 17, 2013, Zhang announced a proof that there are infinitely many pairs of prime numbers that differ by less than 70 million. 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). In a 2013 interview with Nautilus magazine, Zhang said he did not get a job after graduation. (Oct. 12, 2015) Yitang Zhang - the mathematician who solved the bounded gap problem and spent many hours studying in University of Kentucky Libraries in the '90s - will deliver this years Hayden-Howard Lecture, hosted by the UK Department of Mathematics, at 4 p.m. on Thursday, October 15. The following articles are merged in Scholar. Now, even artists are getting in on the story. Zhang arrived at Purdue in January 1985, studied there for six and a half years, and obtained his PhD in mathematics in December 1991. One of the most brilliant minds of our time. Other than that, though, his lectures a theory heavy but help greatly with learning the material. Y Zhang, Y Cheng, W Jiang, Y Ye, Q Lu, H Zhao.
