Sign patterns of graph laplacian eigenvectors

Aktivität: VortragVortrag auf sonstiger Veranstaltung (Science-to-Professionals/Public)


The Laplacian matrix holds a lot of structural information about a given graph. In this talk we give a short introduction in the properties of this matrix and its eigenvectors. In particular we investigate their sign patterns and the number of so called nodal domains which are maximal components where the vector does not change sign.
