Existence of solutions for an impulsive boundary value problem with nonlinear derivative dependence on unbounded intervals via variational methods [PDF]

open access: yes, 2022
In this paper, we employ the critical point theory and iterative methods to establish the existence of solutions for an impulsive boundary value problem with nonlinear derivative dependence on the half-line.

Nonmonotone impulse effects in second‐order periodic boundary value problems

open access: yesAbstract and Applied Analysis, Volume 2004, Issue 7, Page 577-590, 2004., 2004
We deal with the nonlinear impulsive periodic boundary value problem u″ = f(t, u, u′), u(ti+) = Ji(u(ti)), u′(ti+) = Mi(u′(ti)), i = 1, 2, …, m, u(0) = u(T), u′(0) = u′(T). We establish the existence results which rely on the presence of a well‐ordered pair (σ1, σ2) of lower/upper functions (σ1 ≤ σ2 on [0, T]) associated with the problem.

Self-similar voiding solutions of a single layered model of folding rocks [PDF]

open access: yes, 2011
In this paper we derive an obstacle problem with a free boundary to describe the formation of voids at areas of intense geological folding. An elastic layer is forced by overburden pressure against a V-shaped rigid obstacle.

Mild solution of fractional order differential equations with not instantaneous impulses

open access: yesOpen Mathematics, 2015
In this paper, we investigate the boundary value problems of fractional order differential equations with not instantaneous impulse. By some fixed-point theorems, the existence results of mild solution are established.
