SUMMARY:Algebraic Graph Theory - Cristina Dalfó
CLASS:PUBLIC
DESCRIPTION:TITLE: The spectra of lift and factored lifts of graphs or dig
 raphs\n\nSPEAKER:\n\nCristina Dalfó\n\nAFFILIATION:\n Universitat de Llei
 da\n\nLOCATION:\n Please contact Sabrina Lato [/smlato@uwaterloo.ca] for t
 he Zoom\nlink.\n\nABSTRACT: In this talk\, we first explain the path we t
 ook from\ndefining polynomial matrices to a generalization of voltage grap
 hs\nthat we call combined voltage graphs. Moreover\, we give a general\nde
 finition of a matrix associated with a combined voltage graph\, which\nall
 ows us to provide a new method for computing the eigenvalues and\neigenspa
 ces of such graphs.
