Extremal Eigenvalues of Graphs

Türker Bıyıkoğlu
Işık Üniversitesi

Date : Wednesday, March 24, 2010
Time : 14:00
Place : TB 250, Boğaziçi Üniversitesi

Abstract: The fundamental graph properties e.g. coloring, diameter,
isomorphism and connectivity are closely related (or bounded) to the
eigenvalues of matrix representations of these graphs (e.g. adjacency
matrix or Laplacian matrix of the graph). The sharp eigenvalue bounds
for such graph invariants depend on the extremal eigenvalues.
Extremal graph eigenvalue problem is finding a graph in a given graph
class that has the minimum (or maximum) eigenvalue for a given matrix
representation.
I shall talk about these connections between graph properties and
eigenvalues of graphs. I shall present results, methods, difficulties and
possible further research topics on extremal graph eigenvalue
problems. This talk is intended for general audience. No specialist
knowledge is required.

Tea and coffee will be served at 15:00
