The Cauchy–Nicoletti boundary value problem for a sys- tem of ordinary differential equations with pole-type singularities is investigated.. The conditions of the existence,
The focus of our present work is to establish the existence of almost periodic solutions of neutral functional differential equations by using the Razumikhin-type argument.. The
In the present study, using the characterizations of measures of noncompactness we prove a theorem on the existence and local asymptotic stability of solutions for a
During the last decades, several authors considered the problem of existence of mild solutions for semilinear evolution equations with finite delay. When the delay is infinite,
Abstract A multi-point boundary value problem involving the one dimensional p -Laplacian and.. depending on a parameter is studied in this paper and existence of positive solutions
The existence of time optimal controls for problem (P) is proved by this constructive approach which offers a new way to compute the time optimal control.. The rest of the paper
We provide an existence result for a Neumann nonlinear boundary value problem posed on the half-line.. If kernel L is nontrivial then the equation is called resonant and one can
The main new element of our results is a high order exponential asymptotic expansion which extends in a unified way both the classical Cramér–Lundberg approximation and the
