Totally Nonnegative Matrices - Part I of II

10:30 AM-12:30 PM
Potomac

This Session has been Cancelled

A matrix is totally positive (totally nonnegative) if every minor is positive (nonnegative). Though seemingly special, such matrices arise in a remarkable variety, and increasingly many ways, such as in approximation theory, differential equations, statistics, dynamical systems, geometry, algebra, computer aided geometric design, numerical analysis, etc. The purpose of this series is to illustrate the current vitality and deepening understanding of this key class of matrices. Among many recent results, increasing awareness of the elementary bidiagonal factorization, and how to compute it, has made classical results more transparent and subtle problems more approachable.
