DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGARTOS/13/
 ">The S_n-equivariant rational homology of the tropical moduli spaces \\De
 lta_{2\,n}.</a>\nby Claudia Yun (Brown U.) as part of (LAGARTOS) Latin Ame
 rican Real and Tropical Geometry Seminar\n\n\nAbstract\nThe tropical modul
 i space \\Delta_{g\,n} is a topological space that parametrizes isomorphis
 m classes of n-marked stable tropical curves of genus g with total volume 
 1. Its reduced rational homology has a natural structure of S_n-representa
 tions induced by permuting markings. In this talk\, we focus on \\Delta_{2
 \,n} and compute the characters of these S_n-representations for n up to 8
 . We use the fact that \\Delta_{2\,n} is a symmetric \\Delta-complex\, a c
 oncept introduced by Chan\, Glatius\, and Payne. The computation is done i
 n SageMath.\n
