摘要: We derive expression for the subgraph heat kernel and compute the coefficients of the expansion. By using the heat kernel expansions for the Laplacian on a subgraph of a complete graph,we obtain formal expansions for the Green function of the Laplacian. We also obtain the expression of heat kernel for the subgraph of any graphs. These are based on the joint works with Li,Ngai,Wang and Yau.
