The goal of this study is to solve a non-linear matrix equation of the form $ \mathcal{X} = \mathcal{Q} + \sum\limits_{i = 1}^{m} \mathcal{B}_{i}^{*}\mathcal{G} (\mathcal{X})\mathcal{B}_{i} $, where $ \mathcal{Q} $ is a Hermitian positive definite ma

In this work, the following system of nonlinear matrix equations is considered, X1+A∗X1−1A+B∗X2−1B=I and X2+C∗X2−1C+D∗X1−1D=I, where A,B,C, and D are arbitrary n×n matrices and I is the identity matrix of order n. Some conditions for

We use the notions of left- and right-complete quasi-b-metric spaces and partial ordered sets to obtain a couple of common fixed-point results for strictly weakly isotone increasing mappings and relatively weakly increasing mappings, which satisfy a

We consider the system of non-linear matrix equations (NMEs) of the form $$\begin{aligned} {\mathcal {X}}={\mathcal {B}}_{1} + \sum _{i=1}^{k}{\mathcal {A}}_{i}^{*}f\mathcal {(X)}{\mathcal {A}}_{i},\qquad {\mathcal {X}}={\mathcal {B}}_{2} + \sum _{i=
