应数学系张毅超教授的邀请，山东大学6163银河线路检测中心副经理，教育部新世纪优秀人才吕广世教授将于近日来6163银河线路检测中心数学系短期访问，并挑选了数论里几个有趣的问题来做两个报告，欢迎数学系师生踊跃参加。报告具体信息如下：
1、题目：Fourier coefficients of automorphic forms for higher rank groups 时间：6月21日15：30-16：30 地点：格物楼503 摘要：In this talk, I shall introduce some recent results on the distribution of Fourier coefficients of automorphic forms for higher rank groups.In particular, I will talk about the orthogonality between additive characters and Fourier coefficients over primes, and Bombieri-Vinogradov type mean value connected with Fourier coefficients. These results are related to the M/"obius Randomness Principle.
2、题目： Linnik's approximation to Goldbach's conjecture, and other problems
时间：6月22日15：30-16：30 地点：诚格物楼503 摘要：In this general talk, I will talk about various approximations to the famous Goldbach conjecture. In particular, we shall mainly focus on the Linnik almost Goldbach problem, which states that every sufficiently large even number can be written as as the sum of two primes and at most 12 powers of 2.
