Intervals of bifurcation points for semilinear elliptic problems

Advances in Nonlinear Analysis
In this article, we study the behavior of multiple continua of solutions to the semilinear elliptic problem −Δu=λf(u),inΩ,u=0,on∂Ω,\left\{\begin{array}{ll}-\Delta u=\lambda f\left(u),\hspace{1.0em}& \hspace{0.1em}\text{in}\hspace{0.1em}\hspace{0.33em ...

Loop Type Subcontinua of Positive Solutions for Indefinite Concave-Convex Problems

Advanced Nonlinear Studies, 2019
We establish the existence of loop type subcontinua of nonnegative solutions for a class of concave-convex type elliptic equations with indefinite weights, under Dirichlet and Neumann boundary conditions.

Uniqueness of positive radially symmetric solutions for a Schrödinger–Poisson–Slater equation

Advanced Nonlinear Studies
The paper deals with radially symmetric solutions of the following nonlinear Schrödinger–Poisson–Slater equation−Δu+|x|−1∗u2u=μ|u|p−2u,inR3, $${-}{\Delta }u+\left(\vert x{\vert }^{-1}\ast {u}^{2}\right)u=\mu \vert u{\vert }^{p-2}u,\enspace \mathrm{i ...
