SUMMARY:Algebraic Graph Theory Seminar - Chris Godsil
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Cospectral and strongly cospectral vertices

 om:\n MC 5479\n\nABSTRACT:\n\nIf $a$ is a vertex in a graph with adjacency
  matrix $A$\, the\n\\textsl{walk module} generated by $a$ is the $A$-invar
 iant subspace\nspanned by the vectors $A^re_a$\, for $r\\ge0$.\n
