For a simple graph G on n vertices, a real symmetric nxn matrix A is said to be compatible with G, if for different i and j, the (I,j) entry of A is nonzero whenever there is an edge between the vertices i and j, it is zero otherwise. The minimum number of distinct eigenvalues, when minimum is taken over all compatible matrices with G, is denoted by q(G). In this talk, a survey of some known and new results about q(G) is presented.

About the Series
Hosted by NSU’s Halmos College of Natural Sciences and Oceanography Department of Mathematics, the Mathematics Colloquium Series aims to increase awareness of the importance of mathematics and applications in daily life. The series also gives mathematics faculty members and students the opportunity to discuss independent research and share their passion for the subject. For more information, contact Jeffrey W. Lyons, Ph.D., associate professor, at (954) 262-7931.
