Title:Combinatorics of Total Positivity
Seminar:MASS Colloquium
Speaker:Michael Gekhtman, Notre Dame
Abstract:
A totally positive matrix is a matrix with all positive minors. We will review origins and examples of total positivity and show how the key properties of totally positive matrices can be encoded by a purely combinatorial tool - directed planar graphs.
