## [Distinguished Lecture] Small gaps between primes

July 20, 2015 15:00-16:00, 镜春园82号甲乙丙楼的中心报告厅

Abstract: The twin prime conjecture states that there are infinitely many pairs of distinct primes which differ by 2. Until recently this conjecture had seemed to be out of reach with current techniques. However, in 2013, the author proved that there are infinitely many pairs of distinct primes which differ by no more than B with B = 7· 107. The value of B has been considerably improved by Polymath8 (a cooperative team) and Maynard.

In this talk we shall describe the basic ideas which lead to the proofs of the above results. In particular, a breakthrough on the distribution of primes in arithmetic progressions will be introduced.

7 月他在母校北京大学的北京国际数学研究中心 (BICMR) 有一个系列的学术报告: Distribution of Prime Numbers and the Riemann Zeta Function I, II, III. 这个报告分三场, 原定时间是 July 8, 10, 15,  2014 16:00-17:00, 地点是镜春园 78 号院的 77201 室.

BICMR 官网上这个报告的 Abstract 是这么写的:

The distribution of prime numbers is one of the most important subjects in number theory.

There are many interesting problems in this field. It may not be difficult to understand the problems themselves, but the solutions are extremely difficult.

In this series of talks we will describe the application of certain analytic tools to the distribution of prime numbers. In particular, the role played by the Riemann zeta function will be discussed. We will also describe some early and current researches on the Riemann Hypothesis.

These talks are open to everyone in the major of mathematics, including undergraduate students.

8 日下午 4 点, 田刚现身. 因为人比较多, 改为在镜春园82号甲乙丙楼的中心报告厅进行. 主持人刘若川是 1999 年的 IMO 金牌(他本来也是 1998 年中国国家队的队员).

$\zeta(2k)=\sum_{n=1}^\infty\frac1{n^{2k}}=(-1)^{k+1}\frac{(2\pi)^{2k}B_{2k}}{2(2k)!}$

10 日下午 4 点的第二场, 依旧在镜春园82号甲乙丙楼的中心报告厅. 不过, 15 日的一场会在镜春园 78 号院的 77201 室, 16:30 开始.

15 日下午 4:30 的最后一场, 要深入一点. 田刚坐在教室最后一排, 刘若川, 许晨阳坐在教室左边的走廊.张大师谈到有 Goldston, Pintz and Yildirim 的工作, 说他自己最大的贡献是把 $$c$$ 改进为 $$\dfrac14+\dfrac1{1168}$$.

8 月 23 日下午 15:00, 张益唐在清华大学主楼三层接待厅做了题为 “Bounded gaps between primes and relevant problems” 的报告, 这是今年清华大学的华罗庚数学讲座(Loo-Keng Hua Distinguished Lecture). 很荣幸, 14:50 过一点点, 我正要踏完主楼的最后几级台阶, 一辆轿车停下来, 一个老人下来了. 这背影好眼熟, 原来是杨振宁! 哎呀, 张益唐的成就过于突出, 把物理学家都吸引来了! 在此, 祝愿杨老健康长寿!
