Boundary value problems for integro-differential and singular higher-order differential equations

Open Mathematics
We investigate third-order strongly nonlinear differential equations of the type (Φ(k(t)u″(t)))′=f(t,u(t),u′(t),u″(t)),a.e. on[0,T],\left(\Phi \left(k\left(t){u}^{^{\prime\prime} }\left(t)))^{\prime} =f\left(t,u\left(t),u^{\prime} \left(t),{u}^{^{\prime ...

Existence and multiplicity of positive solutions for multiparameter periodic systems

Open Mathematics
We deal with the existence and multiplicity of positive solutions for differential systems depending on two parameters, λ1,λ2{\lambda }_{1},{\lambda }_{2}, subjected to periodic boundary conditions.

Analysis of RLC multi-term fractional boundary value problems

Annals of the West University of Timisoara: Mathematics and Computer Science
This paper addresses the existence of solutions for a boundary value problem characterized by a fractional differential equation involving a multi-term formulation of the Riemann-Liouville-Caputo derivative.

Infinitely many solutions for an instantaneous and non-instantaneous fourth-order differential system with local assumptions

Demonstratio Mathematica
We investigate a class of fourth-order differential system with instantaneous and non-instantaneous impulses. Our technical approach is mainly based on a variant of Clark’s theorem without the global assumptions.

Involvement of three successive fractional derivatives in a system of pantograph equations and studying the existence solution and MLU stability

Demonstratio Mathematica
Developing a model of fractional differential systems and studying the existence and stability of a solution is considebly one of the most important topics in the field of analysis.
