Digraph Branchings and Matrix Determinants

arXiv:2309.05827v3 Announce Type: replace-cross Abstract: We present a version of the matrix-tree theorem, which relates the determinant of a matrix to sums of weights of arborescences of its directed graph representation. Our treatment allows for non-zero column sums in the p...
