Existence of Solutions for a System of Chandrasekhar’s Equation in Banach algebras under weak topology

Amor Fahem, Aref Jeribi, Najib Kaddachi


This paper is devoted to the study of a coupled system within fractional integral equations in suitable Banach algebra. In particular, we are concerned with a quadratic integral equations of Chandrasekhar type. The existence of solutions will be proved by applying fixed point theorem of a 2×2 block operator matrix defined on a nonempty, closed and convex subset of Banach algebra where the entries are weakly sequentially continuous operators.
