Ratikanta Behera, Gayatri Maharana, Jajati Keshari Sahoo

摘要:

本文介绍了矩阵的$E$ -加权核EP和$F$ -加权对偶核EP矩阵的逆的概念。然后,我们得到了一些显式表达式的加权核心EP矩阵的逆通过其他广义逆。进一步讨论了广义加权Moore-Penrose逆的存在性和矩阵的加权核EP矩阵的逆的可加性.除此之外,我们还提出了星型加权核EP和加权核EP星型矩阵类来求解矩阵方程组。我们进一步阐述了这一理论,通过产生一些表示和表征的星加权核心EP和加权核心EP星类矩阵。

英文摘要:

In this paper, we introduce the notation of $E$-weighted core-EP and $F$-weighted dual core-EP inverse of matrices. We then obtain a few explicit expressions for the weighted core-EP inverse of matrices through other generalized inverses. Further, we discuss the existence of generalized weighted Moore-Penrose inverse and additive properties of the weighted core-EP inverse of matrices. In addition to these, we propose the star weighted core-EP and weighted core-EP star class of matrices for solving the system of matrix equations. We further elaborate on this theory by producing a few representation and characterization of star weighted core-EP and weighted core-EP star classes of matrices.
