Nontrivial solutions of discrete Kirchhoff-type problems via Morse theory

open access: yesAdvances in Nonlinear Analysis, 2022
In this article, we study discrete Kirchhoff-type problems when the nonlinearity is resonant at both zero and infinity. We establish a series of results on the existence of nontrivial solutions by combining variational method with Morse theory.

Symmetric results of a Hénon-type elliptic system with coupled linear part

open access: yesOpen Mathematics, 2022
In this article, we study the elliptic system: −Δu+μ1u=∣x∣αu3+λv,x∈Ω−Δv+μ2v=∣x∣αv3+λu,x∈Ωu,v>0,x∈Ω,u=v=0,x∈∂Ω,\left\{\begin{array}{ll}-\Delta u+{\mu }_{1}u=| x\hspace{-0.25em}{| }^{\alpha }{u}^{3}+\lambda v,& x\in \Omega \\ -\Delta v+{\mu }_{2}v=| x ...

Equivalence between a time-fractional and an integer-order gradient flow: The memory effect reflected in the energy

open access: yesAdvances in Nonlinear Analysis, 2022
Time-fractional partial differential equations are nonlocal-in-time and show an innate memory effect. Previously, examples like the time-fractional Cahn-Hilliard and Fokker-Planck equations have been studied.

A Generalized Version of the Lions-Type Lemma

open access: yesAnnales Mathematicae Silesianae, 2023
In this short paper, I recall the history of dealing with the lack of compactness of a sequence in the case of an unbounded domain and prove the vanishing Lions-type result for a sequence of Lebesgue-measurable functions.
