Title: Trees, Leafs, Logs, Palindromes, and the Riordan Group
Abstract: The Riordan group is a useful elementary tool. Some recent applications involve tree structure and a palindromic multiplication for pseudo-involutions.

Combinatorics Seminar- Divided symmetrization and Schubert polynomials
Thursday, 10/10/2019, 6:15pm - 11:59pm
Speaker: Vasu Tewari, UPenn
Date and time: Thursday, October 10, 2:15–3:15pm
Place: Phillips 110
Abstract: The procedure of divided symmetrization was introduced by A. Postnikov in the context of computing volume polynomials of various classes of permutahedra. This procedure takes a multivariate polynomial as input and outputs a scalar, which in many cases is a combinatorially interesting quantity.
