SUMMARY:Workshop / Seminar:the Zero Forcing Number of a Graph
DESCRIPTION:Given a symmetric real matrix\, how does the pattern of zero and nonzero off-diagonal entries affect the possible eigenvalues? In particular\, given a specified pattern\, what is the maximum multiplicity of an eigenvalue in any matrix with that pattern? To answer this question\, we associate a simple graph to every pattern according to the graph's adjacency matrix. A parameter called the zero forcing number of this graph helps us bound the the maximum multiplicity of an eigenvalue\; we define and begin to explore this parameter.
