|Title:||Combinatorics of Total Positivity|
|Speaker:||Michael Gekhtman, Notre Dame|
|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.|
