Fixed points differential equations
WebThe proof relies on transforming the differential equation, and applying Banach fixed-point theorem. By integrating both sides, any function satisfying the differential equation must also satisfy the integral equation A simple proof of existence of the solution is obtained by successive approximations. WebThis paper is devoted to studying the existence and uniqueness of a system of coupled fractional differential equations involving a Riemann–Liouville derivative in the Cartesian product of fractional Sobolev spaces E=Wa+γ1,1(a,b)×Wa+γ2,1(a,b). Our strategy is to endow the space E with a vector-valued norm and apply the Perov fixed point theorem.
