Fractional revival on quasi-abelian Cayley graphs

Yi Fang, Xueyi Huang, Xiaogang Liu +1

Fractional revival, a quantum transport phenomenon critical to entanglement generation in quantum spin networks, generalizes the notion of perfect state transfer on graphs. A Cayle…

Proof of Lew's conjecture on the spectral gaps of simplicial complexes

Xiongfeng Zhan, Xueyi Huang, Huiqiu Lin

As a generalization of graph Laplacians to higher dimensions, the combinatorial Laplacians of simplicial complexes have garnered increasing attention. Let be a simplicial compl…

On the spectral extremal problem of planar graphs

Xiaolong Wang, Xueyi Huang, Huiqiu Lin

The spectral extremal problem of planar graphs has aroused a lot of interest over the past three decades. In 1991, Boots and Royle [Geogr. Anal. 23(3) (1991) 276--282] (and Cao and…

Distance-regular Cayley graphs over (pseudo-) semi-dihedral groups

Xueyi Huang, Lu Lu, Xiongfeng Zhan

Distance-regular graphs are a class of regualr graphs with pretty combinatorial symmetry. In 2007, Miklavič and Potočnik proposed the problem of charaterizing distance-regular Cayl…

Spectral condition for spanning -ended trees in -connected graphs

Jiaxin Zheng, Xueyi Huang, Junjie Wang

For any integer , a spanning -ended tree is a spanning tree with at most leaves. In this paper, we provide a tight spectral radius condition for the existence of a…
