Quasilinear Dirichlet problems with competing operators and convection
The paper deals with a quasilinear Dirichlet problem involving a competing (p,q)-Laplacian and a convection term. Due to the lack of ellipticity, monotonicity and variational structure, the known methods to find a weak solution are not applicable.

A quasilinear problem with fast growing gradient
In this paper we consider the following Dirichlet problem for the $p$-Laplacian in the positive parameters $\lambda$ and $\beta$: [{{array} [c]{rcll}% -\Delta_{p}u & = & \lambda h(x,u)+\beta f(x,u,\nabla u) & \text{in}\Omega u & = & 0 & \text{on}\partial\

Positive Radial Solutions for Singular Quasilinear Elliptic Equations in a Ball
We establish the existence of positive radial solutions for the boundary value problems { −∆pu = λf(u) in B, u = 0 on ∂B, where ∆pu = div(|∇u|p−2∇u), p ≥ 2, B is the open unit ball R , λ is a positive parameter, and f : (0,∞)→ R is p-superlinear at ∞ and

Infinitely many solutions for a class of quasilinear elliptic equations with p-Laplacian in RN
In this paper, we study the multiplicity of solutions for a class of quasilinear elliptic equations with p-Laplacian in RN. In this case, the functional J is not differentiable. Hence, it is difficult to work under the classical framework of the critical

A Note on why Enforcing Discrete Maximum Principles by a simple a Posteriori Cutoff is a Good Idea
Discrete maximum principles in the approximation of partial differential equations are crucial for the preservation of qualitative properties of physical models. In this work we enforce the discrete maximum principle by performing a simple cutoff.

On entire solutions for an indefinite quasilinear system of mixed power
We prove non-existence and existence of entire positive solutions for a Schrodinger quasilinear elliptic system. To prove the non-existence, we combine a carefully-chosen test function with some results that we proved concerning the positivity of a kind ...

A remark on an overdetermined problem in Riemannian Geometry
Let $(M,g)$ be a Riemannian manifold with a distinguished point $O$ and assume that the geodesic distance $d$ from $O$ is an isoparametric function. Let $\Omega\subset M$ be a bounded domain, with $O \in \Omega$, and consider the problem $\Delta_p u = -1$

Fractional differentiability for solutions of the inhomogenous $p$-Laplace system
It is shown that if $p \ge 3$ and $u \in W^{1,p}(\Omega,\mathbb{R}^N)$ solves the inhomogenous $p$-Laplace system \[ \operatorname{div} (|\nabla u|^{p-2} \nabla u) = f, \qquad f \in W^{1,p'}(\Omega,\mathbb{R}^N), \] then locally the gradient $\nabla u ...
