Nonlinear elliptic boundary value problems with convection term and Hardy potential
In this paper, we deal with a nonlinear elliptic problems that incorporate a Hardy potential and a nonlinear convection term. We establish the existence and regularity of solutions under various assumptions concerning the summability of the source term f.

Infinitely many normalized solutions for Schrödinger equations with local sublinear nonlinearity
In this article, we investigate the following Schrödinger equation: −Δu=h(x)g(u)+λuinRN,∫RN∣u∣2dx=au∈H1(RN),\left\{\begin{array}{ll}-\Delta u=h\left(x)g\left(u)+\lambda u\hspace{1.0em}& \hspace{-0.2em}\text{in}\hspace{0.1em}\hspace{0.33em}{{\mathbb{R}}}^{

Existence results for nonlinear degenerate elliptic equations with lower order terms
In this paper, we prove the existence and regularity of solutions of the homogeneous Dirichlet initial-boundary value problem for a class of degenerate elliptic equations with lower order terms. The results we obtained here, extend some existing ones of [

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.

Existence of positive solutions of elliptic mixed boundary value problem
In this paper, we use variational methods to prove two existence of positive solutions of the following mixed boundary value problem: {−Δu=f(x,u),x∈Ω,u=0,x∈σ,∂u∂ν=g(x,u),x∈Γ.

Global existence and finite-time blowup for a mixed pseudo-parabolic r(x)-Laplacian equation
This article is devoted to the study of the initial boundary value problem for a mixed pseudo-parabolic r(x)r\left(x)-Laplacian-type equation. First, by employing the imbedding theorems, the theory of potential wells, and the Galerkin method, we ...
