Dirichlet Problems with an Indefinite and Unbounded Potential and Concave-Convex Nonlinearities [PDF]
Abstract and Applied Analysis, 2012 We consider a parametric semilinear Dirichlet problem with an unbounded and indefinite potential. In the reaction we have the competing effects of a sublinear (concave) term and of a superlinear (convex) term.

Nonlinear, Nonhomogeneous Robin Problems with Indefinite Potential and General Reaction [PDF]
Applied Mathematics & Optimization, 2018 We consider a nonlinear elliptic equation driven by a nonhomogeneous differential operator plus an indefinite potential. On the reaction term we impose conditions only near zero. Using variational methods, together with truncation and perturbation techniques and critical groups, we produce three nontrivial solutions with sign information.

Semilinear neumann equations with indefinite and unbounded potential [PDF]
, 2016 We consider a semilinear Neumann problem with an indefinite and unbounded potential, and a Carathéodory reaction term. Under asymptotic conditions on the reaction which make the energy functional coercive, we prove multiplicity theorems producing three or four solutions with sign information on them.

ON STRONGLY INDEFINITE SCHRÖDINGER EQUATIONS WITH NON-PERIODIC POTENTIAL
Journal of Applied Analysis & Computation, 2023 Summary: This paper is concerned with the non-periodic superlinear Schrödinger equation \(-\Delta u+V(x)u=f(x, u)\), \(u\in H^1(\mathbb{R}^N)\). Here, the Shrödinger operator \(-\Delta + V\) is strongly indefinite, that is, possesses a infinite dimensional negative space, which leads to more difficulty in verifying the compactness conditions.

On a Kirchhoff type problems with potential well and indefinite potential
Electronic Journal of Differential Equations, 2015 In this paper, we study the following Kirchhoff type problem:% $$ \left\{\aligned&-\bigg(α\int_{\bbr^3}|\nabla u|^2dx+1\bigg)Δu+(λa(x)+a_0)u=|u|^{p-2}u&\text{ in }\bbr^3,\\% &u\in\h,\endaligned\right.\eqno{(\mathcal{P}_{α,λ})}% $$ where ...

The Syntax of Polish jeden ‘One’ as an Indefinite Determiner [PDF]
, 2022 The current literature on Polish jeden ‘one’ focuses on its numeral status, though there is evidence that it is grammaticalizing into an indefinite determiner.
