MS-24 Zero Forcing: Its Variations and Applications (Zero Forcing)

Organizers: Daniela Ferrero (Texas State University), Mary Flagg (University of St. Thomas), and Michael Young (Iowa State University)

Zero forcing was introduced as a graph theoretic tool for obtaining an upper bound on the maximum nullity of real symmetric matrices whose nonzero pattern of off-diagonal entries is defined by a given graph. The minimum rank problem was motivated by the inverse eigenvalue problem. Independently, zero forcing was introduced by mathematical physicists studying control of quantum systems. Zero forcing has yielded many interesting results in linear algebra. Even more connections have been discovered, modeling problems in disciplines as diverse as theoretical biology and electrical engineering. The goal of our mini-symposium is to provide a forum for researchers in different variations and applications of zero forcing to share ideas and learn of new techniques that will transfer across applications to advance the state of the art in many directions.
