The AMU Faculty of Physic warmly invite you to another MTPR Seminar.
This time prof. Charles R Johnson from the Department of Mathematics, The College of William & Mary, Williamsburg, the USA, will give a talk on "Eigenvalues, multiplicities and graphs".
The event will be held on March 15, 2023, between 1 p.m. - 2 p.m.
Consider all real symmetric or complex Hermitian matrices with a directed graph G. We give an introduction to the study of the possible multiplicities of the eigenvalues of such matrices. For example, when G is a tree, the maximum multiplicity is the path cover number of the tree. We may also discuss the non-Hermitian case. Some of the issues covered by the talk were inspired by the problems originating from physics.
