SEMINAR: Groups and Combinatorics Seminar: Compositions of n and an application to the covering number of the symmetric groups

Groups and Combinatorics Seminar

Pablo Spiga (University of Milano-Bicocca)

will speak on

Compositions of n and an application to the covering number of the symmetric groups

at 1pm in MLR2 on Tuesday 21st of August

Abstract: Given a positive integer n, a k-composition of n is an ordered sequence of k positive integers summing up to n. In this short talk, we are interested on the number of k-compositions satisfying some "coprimeness" condition. As an application we give a Classification-free proof of some results on the covering number of the symmetric group.

All welcome
