The Smith normal form of Laplacian matrices of simplicial annuli and high dimensional trees

Carlos A. Alfaro, Jesús Uriel Medrano, Juan Pablo Serrano +2

Inspired by the generalization of the formula of determinant of the distance matrix of trees to $k$ -trees, we study the Smith normal form of Laplacian matrices associated with some…

The Smith normal form of distance matrices of high dimensional trees

Carlos A. Alfaro, Jesús Uriel Medrano, Iván Téllez Téllez

Graham-Lovász-Pollak \cite{GL,GP} obtained the celebrated formula $det (D (T_{n + 1})) = (- 1)^{n} n 2^{n - 1},$ for the determinant of the distance matrix $D (T_{n + 1})$ for any t…
