Muhammad Shahzad Department of Mathematics, Hazara University Mansehra, Khyber Pakhtunkhwa, Pakistan. Journal Article 2025 11 09 In this article, we study a coupled systems of generalized Chandrasekhar quadratic integral equations,which is widely applicable in various disciplines of science and technology. By using the contraction mappingprinciple and successive approximation, we develop suffcient conditions for existence and uniqueness ofthe solution. Also, an example is provided to illustrate our main results.
