Fixed points of subadditive maps with an application to a system of Volterra-Fredholm type integrodifferential equations (Q2298711)

Summary: In this paper, some fixed-point theorems are established for strongly subadditive maps on \(C \left(\Omega, \Upsilon\right)\) (where \(C \left(\Omega, \Upsilon\right)\) denotes the space of \(\Upsilon \)-valued continuous functions on a compact Hausdorff space \(\Omega\) and \(\Upsilon\) is a unital Banach algebra). Finally, the result is applied to prove the existence and uniqueness of a solution for a system of nonlinear integrodifferential equations.
