To strengthen the established results, we presented a positive example. In applications, we found the existence of the solution to nonlinear matrix equations, and unique solutions of two scale fractal hybrid fractional differential equations in CATp(0).enFixed point theorem on CATp(0) metric spaces with applications in solving matrix equations and fractional differential equationsArticle
