“Character polynomials for symmetric groups”
Abstract: For every positive integer r, the number of cycles of length r in the cycle decomposition of a permutation is a class function X_r which is simultaneously defined on every symmetric group. A polynomial in terms of X_r’s is called a character polynomial, describing a sequence of (virtual) S_n representations for every n. In this talk I will discuss how such sequences arise in particular examples of interest and time permitting explain a general framework for their occurence.
