The next session(s) of the seminar.

The next (186th) session will be held on Thursday, July 19, in the room no. 311 at 14.00.

Speaker: Zhi-Wei Sun (Nanjing University)
Title: Determinants, Permutations and Additive Combinatorics.

Abstract:

In this talk we will introduce some new problems and related progress on determinants involving Legendre symbols, circular permutations and additive combinatorics. For example, we conjecture that for any finite subset A of an additive cyclic group G with |A|=n>3 there is a circular permutation a1, …, an of the elements of A such that all the n sums

a1+a2+a3, a2+a3+a4, …, an-2+an-1+an, an-1+an+a1, an+a1+a2

are pairwise distinct. The speaker has proved this when G is the infinite cyclic group Z.


After session tea in the marble hall will be organized.
