Positive solutions for second-order differential equations of Kirchhoff type on the half-line
AbstractThe aim of the present paper is to study the existence of nontrivial nonnegative solutions for asecond-order boundary value problem…
A unified variational approach to discontinuous differential equations
AbstractA direct variational technique involving Clarke generalized gradient is used to treat general boundary value problems with discontinuous nonlinearities. Based…
Fixed point–critical point hybrid theorems and application to systems with partial variational structure

Study on Integrodifferential Evolution Systems with Nonlocal Initial Conditions
AbstractThe work is concerned with systems of abstract integrodifferential equations with general nonlocal initial conditions. To allow the nonlinear terms…
On the Durrmeyer-type variant and generalizations of Lototsky–Bernstein operators
Abstract The starting points of the paper are the classic Lototsky–Bernstein operators. We present an integral Durrmeyer-type extension and investigate…
