Gluing of Graph Laplacians and Their Spectra
Ivan Contreras, Michael Toriyama, Chengzheng Yu
We study two different types of gluing for graphs: interface (obtained by choosing a common subgraph as the gluing component) and bridge gluing (obtained by adding a set of edges t…

Hyperwalk Formulae for Even and Odd Laplacians in Finite CW-Hypergraphs
Ivan Contreras, Sarah Loeb, Chengzheng Yu
In this note we provide a combinatorial interpretation for the powers of the hypergraph Laplacians. Our motivation comes from the discrete formulation of quantum mechanics and ther…

Super-Walk Formulae for Even and Odd Laplacians in Finite Graphs
Chengzheng Yu
The number of walks from one vertex to another in a finite graph can be counted by the adjacency matrix. In this paper, we prove two theorems that connect the graph Laplacian with…
