Abstract We establish a Monch type generalization of the Eilenberg-Montgomery fixed point theorem for multi-valued maps with acyclic values. AuthorsRadu…
AbstractThe paper deals with existence, uniqueness and iterative approximation of solutions to boundary value problems for second-order differential equations on…
AbstractWe develop continuation technique to obtain periodic solutions for superlinear planar differential systems of first order with impulses. Our approach…
Abstract The paper is devoted to the study of the neutral differential equation with delay \(x^{\prime}(t)=f(t,x\left( t\right) ,(\theta \left(t\right) ),x^{\prime}(\theta…
