An Application of Set Theory in Quasi-Paracompactness
《Journal of Mathematical Research with Applications》2022年第6期653-657,共5页Xiangeng ZHOU Shou LIN

In 1977,Yingming Liu introduced quasi-paracompactness and proved that under 2^(ω1)>2~ωevery separable normal quasi-paracompact space is a paracompact space,which is a result of set-theoretic topology.In this paper w...

Estimations for the Spectral Radius of Nonnegative Tensors
《Journal of Mathematical Research with Applications》2020年第5期487-492,共6页Aiquan JIAO 
Supported by the National Natural Science Foundation of China(Grant No.11601473);the Doctoral Innovation Found of Hebei University of Engineering(Grant No.112/SJ010002142)。
In this paper, a lower bound and an upper bound for the spectral radius of nonnegative tensors are obtained. Our new bounds are tighter than the corresponding bounds obtained by Li et al.(J. Inequal. Appl. 2015). A nu...

Minimal Critical Sets of Refined Inertias for Irreducible Sign Patterns of Order 3
《Journal of Mathematical Research with Applications》2020年第3期246-262,共17页Yajing WANG Yubin GAO Yanling SHAO 
Supported by Shanxi Province Science Foundation for Youths(Grant No.201901D211227).
Let S be a nonempty, proper subset of all possible refined inertias of real matrices of order n. The set S is a critical set of refined inertias for irreducible sign patterns of order n,if for each n × n irreducible ...

A New Class AOR Preconditioner for L-Matrices被引量：3
《Journal of Mathematical Research with Applications》2019年第1期101-110,共10页Reza BEHZADI 
Hadjidimos(1978) proposed a classical accelerated overrelaxation(AOR) iterative method to solve the system of linear equations, and discussed its convergence under the conditions that the coefficient matrices are irre...

Repeated-Root Self-Dual Negacyclic Codes over Finite Fields
《Journal of Mathematical Research with Applications》2016年第3期275-284,共10页Xiuli LI 
Supported by Reward Fund for Outstanding Young and Middle-Aged Scientists of Shandong Province(Grant No.BS2011DX011);Qingdao Postdoctoral Fund(Grant No.861605040007)
Let F_q be a finite field with q = p^m, where p is an odd prime. In this paper, we study the repeated-root self-dual negacyclic codes over Fq. The enumeration of such codes is investigated. We obtain all the self-dual...
