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 Cristina Dalfó\n\nAFFILIATION:\n Universitat de Lleid
 a\n\nLOCATION:\n Please contact Sabrina Lato for Zoom Link.\n\nABSTRACT: 
 In this talk\, we first explain the path we took from\ndefining polynomial
  matrices to a generalization of voltage graphs\nthat we call combined vol
 tage graphs. Moreover\, we give a general\ndefinition of a matrix associat
 ed with a combined voltage graph\, which\nallows us to provide a new metho
 d for computing the eigenvalues and\neigenspaces of such graphs.
