This workshop, sponsored by AIM and the NSF, will be devoted to the theory of zero forcing and its applications. Zero forcing is a propagation on graphs described by the following process. Consider a graph G and color each of its vertices blue or white. A blue vertex v can force a white vertex w to be blue if w is the only white vertex in the neighborhood of v. A zero forcing set of G is a set of vertices SaS‚V(G) such that if the vertices of S are colored blue and the remaining vertices are colored white, then every vertex can eventually become blue, after a repeated application of the forcing process. The zero forcing number of G,Z(G), is the minimum cardinality of a zero forcing set.
