The spectra of Laplace operators on covering simplicial complexes

Yi-Zheng Fan, Yi-Min Song, Yi Wang

We give a decomposition of the Laplace operator (in matrix form) of a covering simplicial complex as a direct sum of several matrices, one of which is the Laplace operator of the b…

Hypergraph coverings and Ramanujan Hypergraphs

Yi-Min Song, Yi-Zheng Fan, Zhengke Miao

In this paper we investigate Ramanujan hypergraphs by using hypergraph coverings. We first show that the spectrum of a -fold covering of a connected hypergraph con…

Asymptotic Behavior of the Zhang--Kawazumi's phi-invariant

Yinchong Song

The phi-invariant was introduced by Shou-Wu Zhang and Nariya Kawazumi. We study the continuity property of the phi-invariants for degenerating graphs, and show that this continuity…
