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