Alternating sign property of the perfect matching derangement graph
It was conjectured in the monograph 9] by Godsil and Meagher and in the article 10] by Lindzey that the per-fect matching derangement graph M2n possesses the alter-nating sign property, that is, for any integer partition A = (A1, . . . , Ar) diamond -n, the sign of the eigenvalue eta lambda of M2n i...
