Common fixed point theorems for rational F R \(F_{\mathcal{R}}\) -contractive pairs of mappings with applications
In this paper, we study the existence of solution for the following non-linear matrix equations: X=Q+∑i=1nAi∗XAi−∑i=1nBi∗XBi,X=Q+∑i=1nAi∗ϒ(X)Ai, where Q is a Hermitian positive definite matrix, Ai\(A_{i}\), Bi\(B_{i}\) are arbitrary m×m\(m\times m\) matrices and ϒ:H(m)→P(m)\(\varUpsilon: \mathcal{H}...

Summary: | In this paper, we study the existence of solution for the following non-linear matrix equations: X=Q+∑i=1nAi∗XAi−∑i=1nBi∗XBi,X=Q+∑i=1nAi∗ϒ(X)Ai, where Q is a Hermitian positive definite matrix, Ai\(A_{i}\), Bi\(B_{i}\) are arbitrary m×m\(m\times m\) matrices and ϒ:H(m)→P(m)\(\varUpsilon: \mathcal{H}(m)\rightarrow \mathcal{P}(m)\) is an order preserving continuous map such that ϒ(0)=0\(\varUpsilon (0)=0\). To this aim, we establish several common fixed point theorems for two mapping satisfying a rational FR\(F_{\mathcal{R}}\)-contractive condition, where R\(\mathcal{R}\) is a binary relation. |
