In this paper we survey some recent results on the existence and multiplicity of radial solutions for Neumann problems in a ball and in an annular domain, associated to pendulum-like perturbations of mean curvature operators in Euclidean and Minkowski spaces and of the p-Laplacian operator. Our approach relies on the Leray-Schauder degree, upper and lower solutions method, and critical point theory.
Existence results for parametric boundary value problems involving the mean curvature operator
Nonlinear Differential Equations and Applications NoDEA, 2014
In this note we propose a variational approach to a parametric differential problem where a prescribed mean curvature equation is considered. In particular, without asymptotic assumptions at zero and at infinity on the potential, we obtain an explicit positive interval of parameters for which the problem under examination has at least one nontrivial and nonnegative solution.
New existence results for some periodic and Neumann-Steklov boundary value problems with ϕ-Laplacian
Boundary Value Problems, 2016
We study the existence of solutions of the quasilinear equation (φ(u (t))) = f (t, u(t), u (t)), a.e. t ∈ [0, T], with periodic or nonlinear Neumann-Steklov boundary conditions, where φ : ]-a, a[→ R with 0 < a < +∞ is an increasing homeomorphism such that φ(0) = 0. Combining some sign conditions and the lower and upper solution method, we obtain the existence of solutions when there exists one lower solution or one upper solution.
