Title:  REGULAR GRAPHS MEETING HOFFMAN BOUNDS

Speaker: Yuqing Chen (Professor, Wright State University)

Time: 9:30-11:30,  May 7, 2019

Venue: 200-9, Sir Run-Run Shaw Business Building

Abstract:

In this talk we discuss regular graphs that meet the Hoffman bounds and their behaviors 

under normal product, tensor product and Cartesian product. The results generalize a theorem of 
Alon, Dinur, Friedgut and Sudakov. Our methods require only basic linear algebra.
