The adjacency matrices and the transition matrices related to random walks on graphs
Tomohiro Ikkai, Hiromichi Ohno, Yusuke Sawada
A pointed graph induces a family of transition matrices in Wildberger's construction of a hermitian hypergroup via a random walk on starting from . We will give…

Hypergroups derived from random walks on some infinite graphs
Tomohiro Ikkai, Yusuke Sawada
Wildberger gave a method to construct a finite hermitian discrete hypergroup from a random walk on a certain kind of graphs. In this article, we reveal that his method is applicabl…
