Solvability of a 2 × 2 block operator matrix of Chandrasekhar type on a Banach algebra


H H G Hashem




In this paper, we study the existence of solutions for a system of quadratic integral equations of Chandrasekhar type by applying fixed point theorem of a 2×2 block operator matrix defined on a nonempty bounded closed convex subsets of Banach algebras where the entries are nonlinear operators.
