张量积下核逆的扰动界

This paper introduces the Hartwig and Spindelb(o)ck decomposition for tensors and the definition of Tensor-core inverse.Then several properties and representations of Tensor-core inverse,are investigated.Further,we present some perturbation bounds for the Tensor-core inverse based on the T-product.     

Perturbation of the Weighted T-Core-EP Inverse of Tensors Based on the T-Product

In this paper,we extend the notion of the T-Schur decomposition to the weighted T-core-EP decomposition.Next,the weighted T-core-EP inverse of rectangular tensors is defined by a system,and its existence and uniqueness are obtained.Furthermore,the perturbation of the weighted T-core-EP inverse is studied under several conditions,and the relevant examples are provided to verify the perturbation bounds of the weighted T-core-EP inverse of tensors.     

具有t-范数的模糊M-半群的性质

本文利用范数,引入M-半群的T-模糊M-子半群的概念,刻划其性质和特征。进一步,我们给出T-模糊M-子半群R与T-模糊M-子半群S的直积是T-模糊M-子半群这一结论。同时,我们证明了T-模糊M-子半群可分解成T-模糊M-子半群的直积。     

T-乘积下张量广义逆及其广义Cayley-Hamilton定理北大核心CSCD

本文通过张量在T-乘积下的T-Moore-Penrose逆、T-Drazin逆以及T-corenilpotent分解定理,引入三阶F-square(正面方的)张量在T-乘积下的T-DMP逆与TCMP逆的定义,同时给出它们的若干刻画和性质.最后将三阶张量的Cayley-Hamilton定理推广到张量的T-Drazin逆与T-DMP逆上,并给出例子进行验证.
