Existence of solutions for fractional differential inclusions with nonlocal Riemann-Liouville integral boundary conditions

Bashir AhmadSotiris Ntouyas — 2014

Mathematica Bohemica

In this paper, we discuss the existence of solutions for a boundary value problem of fractional differential inclusions with nonlocal Riemann-Liouville integral boundary conditions. Our results include the cases when the multivalued map involved in the problem is (i) convex valued, (ii) lower semicontinuous with nonempty closed and decomposable values and (iii) nonconvex valued. In case (i) we apply a nonlinear alternative of Leray-Schauder type, in the second case we combine the nonlinear alternative...

Nonlinear fractional differential inclusions with anti-periodic type integral boundary conditions

Bashir AhmadSotiris K. Ntouyas — 2012

Discussiones Mathematicae, Differential Inclusions, Control and Optimization

This article studies a boundary value problem of nonlinear fractional differential inclusions with anti-periodic type integral boundary conditions. Some existence results are obtained via fixed point theorems. The cases of convex-valued and nonconvex-valued right hand sides are considered. Several new results appear as a special case of the results of this paper.

A study of second order differential inclusions with four-point integral boundary conditions

Bashir AhmadSotiris K. Ntouyas — 2011

Discussiones Mathematicae, Differential Inclusions, Control and Optimization

In this paper, we discuss the existence of solutions for a four-point integral boundary value problem of second order differential inclusions involving convex and non-convex multivalued maps. The existence results are obtained by applying the nonlinear alternative of Leray Schauder type and some suitable theorems of fixed point theory.

A note on rapid convergence of approximate solutions for second order periodic boundary value problems

Rahmat A. KhanBashir Ahmad — 2005

Archivum Mathematicum

In this paper, we develop a generalized quasilinearization technique for a nonlinear second order periodic boundary value problem and obtain a sequence of approximate solutions converging uniformly and quadratically to a solution of the problem. Then we improve the convergence of the sequence of approximate solutions by establishing the convergence of order k ( k 2 ) .

Existence theory for sequential fractional differential equations with anti-periodic type boundary conditions

Mohammed H. AqlanAhmed AlsaediBashir AhmadJuan J. Nieto — 2016

Open Mathematics

We develop the existence theory for sequential fractional differential equations involving Liouville-Caputo fractional derivative equipped with anti-periodic type (non-separated) and nonlocal integral boundary conditions. Several existence criteria depending on the nonlinearity involved in the problems are presented by means of a variety of tools of the fixed point theory. The applicability of the results is shown with the aid of examples. Our results are not only new in the given configuration...
