Title: Inverse eigenvalue problem of a graph

Speaker: Jephian C.-H. Lin Affiliation: National Sun Yat-sen University Location: Please contact Sabrina Lato for Zoom link

Abstract:  We often encounter matrices whose pattern (zero-nonzero, or sign) is known while the precise value of each entry is not clear. Thus, a natural question is what we can say about the spectral property of matrices of a given pattern. When the matrix is real and symmetric, one may use a simple graph to describe its off-diagonal nonzero support.
