Multiple solutions of nonlinear fractional elliptic equations via Morse theory

Electronic Journal of Differential Equations, 2017
This article concerns the existence and multiplicity of weak solutions of the nonlinear fractional elliptic problem. We extend some well known results of semilinear Laplacian equations to the nonlocal fractional setting. Using the variational methods

Double phase elliptic inclusions with convection and logarithmic perturbed terms

Bulletin of Mathematical Sciences
This paper deals with a new double phase elliptic inclusion (DPEI) formulated by a double phase partial differential operator with logarithmic perturbation, a general multivalued convection term defined in the domain and a general multivalued term ...

Existence of multiple positive solutions to integral boundary value systems with boundary multiparameters

Boundary Value Problems, 2018
We establish the existence, nonexistence, and multiplicity of positive solutions to semilinear elliptic systems with integral boundary conditions when positive multiparameters vary on the boundary.

On the Sub and Supersolution Method for Nonlinear Elliptic Equations with a Convective Term, in Orlicz Spaces

Mathematics
In this note we provide an overview of some existence (with sign information) and regularity results for differential equations, in which the method of sub and supersolutions plays an important role.

Positive solutions for concave-convex type problems for the one-dimensional $\phi$-Laplacian

Electronic Journal of Qualitative Theory of Differential Equations
Let $\Omega=(a,b)\subset\mathbb{R}$, $0\leq m,n\in L^{1}(\Omega)$, $\lambda,\mu>0$ be real parameters, and $\phi: \mathbb{R}\rightarrow\mathbb{R}$ be an odd increasing homeomorphism.
