Maximum and antimaximum principles for the $p$-Laplacian with weighted Steklov boundary conditions

open access: yesElectronic Journal of Differential Equations, 2020
We study the maximum and antimaximum principles for the p-Laplacian operator under Steklov boundary conditions with an indefinite weight $$\displaylines{ -\Delta_p u + |u|^{p-2}u = 0 \quad \text{in }\Omega, \cr |\nabla u|^{p-2}\frac{\partial u ...

Uniqueness of positive solutions for boundary value problems associated with indefinite ϕ-Laplacian-type equations

open access: yesOpen Mathematics, 2021
This paper provides a uniqueness result for positive solutions of the Neumann and periodic boundary value problems associated with the ϕ-Laplacian equation (ϕ(u′))′+a(t)g(u)=0,(\phi \left(u^{\prime} ))^{\prime} +a\left(t)g\left(u)=0, where ϕ is a ...

Nonlinear concave-convex problems with indefinite weight [PDF]

open access: yes, 2021
We consider a parametric nonlinear Robin problem driven by the p-Laplacian and with a reaction having the competing effects of two terms. One is a parametric (Formula presented.) -sublinear term (concave nonlinearity) and the other is a (Formula ...

On Indefinite Sums Weighted by Periodic Sequences [PDF]

open access: yesResults in Mathematics, 2019
For any integer $q\geq 2$ we provide a formula to express indefinite sums of a sequence $(f(n))_{n\geq 0}$ weighted by $q$-periodic sequences in terms of indefinite sums of sequences $(f(qn+p))_{n\geq 0}$, where $p\in\{0,\ldots,q-1\}$. When explicit expressions for the latter sums are available, this formula immediately provides explicit expressions ...

Indefinite Eigenvalue Problems for p-Laplacian Operators with Potential Terms on Networks

open access: yesAbstract and Applied Analysis, 2014
We address some forward and inverse problems involving indefinite eigenvalues for discrete p-Laplacian operators with potential terms. These indefinite eigenvalues are the discrete analogues of p-Laplacians on Riemannian manifolds with potential terms ...

Principal Eigenvalues with Indefinite Weight Functions [PDF]

open access: yesTransactions of the American Mathematical Society, 1997
Both existence and non-existence results for principal eigenvalues of an elliptic operator with indefinite weight function have been proved. The existence of a continuous family of principal eigenvalues is demonstrated.

A monotone iteration for a nonlinear Euler-Bernoulli beam equation with indefinite weight and Neumann boundary conditions

open access: yesOpen Mathematics, 2022
In this article, we focus on the existence of positive solutions and establish a corresponding iterative scheme for a nonlinear fourth-order equation with indefinite weight and Neumann boundary conditions y(4)(x)+(k1+k2)y″(x)+k1k2y(x)=λh(x)f(y(x)),x∈[0,1]
