Maximum principle for a stochastic delayed system involving terminal state constraints [PDF]

open access: yesJournal of Inequalities and Applications, 2017
We investigate a stochastic optimal control problem where the controlled system is depicted as a stochastic differential delayed equation; however, at the terminal time, the state is constrained in a convex set.

Existence results for a sublinear second order Dirichlet boundary value problem on the half-line [PDF]

open access: yesOpuscula Mathematica, 2020
In this paper we study the existence of nontrivial solutions for a boundary value problem on the half-line, where the nonlinear term is sublinear, by using Ekeland's variational principle and critical point theory.

Generalized Ekeland’s variational principle with applications

open access: yesJournal of Inequalities and Applications, 2019
By using the concept of Γ-distance, we prove EVP (Ekeland’s variational principle) on quasi-F-metric (q-F-m) spaces. We apply EVP to get the existence of the solution to EP (equilibrium problem) in complete q-F-m spaces with Γ-distances.

Existence of solution for a Kirchhoff type problem involving the fractional p-Laplace operator

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
