Bibekananda Sitha, Jajati Keshari Sahoo, Nestor Thome

AI总结:

本文提出对偶方阵的对偶核心-EP广义逆,分析其存在唯一性并给出基于对偶Drazin和MP逆的公式,建立对偶核心-EP分解及相关广义逆关系,并应用于不相容线性对偶方程组求解。

摘要:

本文针对对偶方阵引入一种新型广义逆,称为对偶核心-EP广义逆(简称DCEPGI)。我们分析了DCEPGI逆的存在性与唯一性,并利用对偶Drazin逆和对偶MP逆给出其紧凑公式。此外,还得到了若干基于核心-EP分解的刻画。我们提出一种新的对偶矩阵分解,称为对偶方阵的对偶核心-EP分解。同时,建立了与其他对偶广义逆的一些关系。作为应用,推导了某些不相容线性对偶方程组的解。

英文摘要:

In this work, we introduce a new type of generalized inverse called dual core-EP generalized inverse (in short DCEPGI) for dual square matrices. We analyze the existence and uniqueness of the DCEPGI inverse and its compact formula using dual Drazin and dual MP inverse. Moreover, some characterizations using core-EP decomposition are obtained. We present a new dual matrix decomposition named the dual core-EP decomposition for square dual matrices. In addition, some relationships with other dual generalized inverses are established. As an application, solutions to some inconsistent system of linear dual equations are derived.
