SUMMARY:Algebraic Combinatorics Seminar - Krystal Guo
CLASS:PUBLIC
DESCRIPTION:TITLE: Inverses of Trees\n\nSpeaker:\n Krystal Guo\n\nAffiliat
 ion:\n Centre de Recherches Mathématiques & Université de Montréal\n\nR
 oom:\n MC 5417\n\nABSTRACT:\n\nA tree is invertible if and only if it has
  a perfect matching.\n\nGodsil considers an invertible tree T and finds t
 hat the inverse of\nthe adjacency matrix has entries in {0\, ±1} and is 
 the signed\nadjacency matrix of a graph which contains T.
