An Analytical Survey on the Solutions of the Generalized Double-Order φ-Integrodifferential Equation
Publikováno v:
Journal of Function Spaces, Vol 2021 (2021)
We study the existence of solutions for a newly configured model of a double-order integrodifferential equation including φ-Caputo double-order φ-integral boundary conditions. In this way, we use the Krasnoselskii and Leray-Schauder fixed point res

Existence results for a second order boundary value problem for functional differential equation, are givn. The results are based on the nonlinear Alternative, of Leray-Schauder and rely on a priori bounds on solutions. These results are generalizati

In this paper, using a simple and classical application of the Leray-Schauder degree theory, we study the existence of solutions of the following boundary value problem for functional differential equations x″(t)+f(t,xt,x′(t))=0, t∈[0,T]x0+αx

Values of λ are determined for which there exist positive solutions of the system of dynamic equations, uΔΔ(t)+λa(t)f(v(Ã(t)))=0, vΔΔ(t)+λb(t)g(u(Ã(t)))=0, for t∈[0,1]T, satisf
