Title |
Symmetric bicolored trees and symmetric tropical ranks |
Abstract |
In this talk I will define and investigate symmetric bicolored trees, the symmetric versions of the bicolored trees studied by Markwig and Yu. In particular, I’ll show that a special subset of these symmetric bicolored trees, those with an “unbranched stem”, form a pure-dimensional simplicial complex, and that this complex is shellable. I’ll then describe a relationship between these symmetric bicolered trees with unbranched stems, or “happy trees”, and the notion of the symmetric tropical rank of a matrix. |
