Tensor Spectral Stability for Uniform Hypergraphs with Bounded Matching Number
Yi Xu, Yi-Zheng Fan
We establish a tensor spectral stability theorem for uniform hypergraphs with bounded matching number. More precisely, for fixed integers and , and sufficiently l…
Generalized spectral Turán problems for disjoint cliques
Yi Xu, Yi-Zheng Fan
The generalized Turán number denotes the maximum number of copies of in an -vertex -free graph. Let be the disjoint union of copies of…
Application of the microscopic optical potential of chiral effective field theory in astrophysical neutron-capture reactions
Bing Wang, Dong Bai, Yi Xu
A state-of-the-art microscopic global nucleon-nucleus optical potential has been developed by Whitehead, Lim, and Holt (WLH) within the framework of many-body perturbation theory,…
Spectral conditions of complement for some graphical properties
Guidong Yu, Yi Fang, Yi Xu
L.H. Feng at el \cite{feng4} present sufficient conditions based on spectral radius for a graph with large minimum degree to be -path-coverable and -Hamiltonian. Motivated by…
