Existence and regularity results for some singular elliptic problems

, 2007
We are interested in the study of existence, uniqueness and regularity of solutions for nonlinear elliptic problems whose model is the linear boundary value problem [GRAPHICS] where 0 is an element of ohm.

Global multiplicity of positive solutions for anisotropic $(p,q)$-Robin boundary value problems with an indefinite potential term

Electronic Journal of Qualitative Theory of Differential Equations
We consider a nonlinear Robin problem driven by the anisotropic $(p,q)$-Laplacian plus an indefinite potential term. In the reaction, we have the competing effects of a parametric concave (sublinear) term perturbed by a superlinear one (concave-convex ...

Regularity on the interior for the gradient of weak solutions to nonlinear second-order elliptic systems

Electronic Journal of Differential Equations, 2013
We consider weak solutions to the Dirichlet problem for nonlinear elliptic systems. Under suitable conditions on the coefficients of the systems we obtain everywhere H"older regularity on the interior for the gradients of weak solutions.

Compensation phenomena in geometric partial differential equations [PDF]

In this thesis we present optimal and improved estimates for systems of critical elliptic PDE which arise as generalisations of natural geometric problems.

Resonant (p,q)-equations with Robin boundary condition

Electronic Journal of Differential Equations, 2018
We consider a nonlinear nonhomogeneous Robin problem that has the sum of a p-Laplacian and a q-Laplacian (a (p,q)-equation). The reaction term is a Caratheodory function which is resonant at $\pm\infty$ with respect to any nonprincipal variational ...
