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. WebTheorem: Let P be a fixed point of g (x), that is, P = g ( P). Suppose g (x) is differentiable on [ P − ε, P + ε] for some ε > 0 and g (x) satisfies the condition g ′ ( x) ≤ L < 1 for all x ∈ [ P − ε, P + ε]. Then the sequence x i + 1 = g ( x i), with starting point x 0 ∈ [ P − ε, P + ε], converges to P. ray horner show
