An existence result for a quasilinear degenerate problem in $\mathbb{R}^N$

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
In this paper we study an existence result of the quasilinear problem $-\mbox{div}[\phi{'}(|\nabla u|^2)\nabla u] + a(x)|u|^{\alpha-2}u = |u|^{\gamma-2}u + |u|^{\beta-2}u$ in $\mathbb{R}^N (N\geq 3)$, where $\phi(t)$ behaves like $t^{q/2}$ for small $t ...

EXISTENCE RESULTS FOR VECTOR NONLINEAR INEQUALITIES

open access: yesCommunications of the Korean Mathematical Society, 2003
Summary: The purpose of this paper is to consider some existence results for vector nonlinear inequalities without any monotonicity assumption. As consequences of our main result, we give some existence results for vector equilibrium problem, vector variational-like inequality problem and vector variational inequality problems as special cases.

The Existence Result for a p-Kirchhoff-Type Problem Involving Critical Sobolev Exponent

open access: yesJournal of Function Spaces, 2023
In this paper, by using the mountain pass theorem and the concentration compactness principle, we prove the existence of a positive solution for a p-Kirchhoff-type problem with critical Sobolev exponent.

Existence Results for Constrained Quasivariational Inequalities [PDF]

open access: yesAbstract and Applied Analysis, 2013
We deal with a constrained quasivariational inequality under a general form. We study existence of solutions in two situations depending on whether the set of constraints is bounded or possibly unbounded.

An existence and qualitative result for discontinuous implicit differential equations

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2018
LetT > 0 and Y ⊆ R^n. Given a function f:[0,T]×R^n×Y → R,we consider the Cauchy problem f(t,u,u′) = 0 in [0,T], u(0) = ξ . We prove an existence and qualitative result for the generalized solutions of the above problem. In particular, our result does not

On the Existence of Pure Strategy Nash Equilibria in Large Games [PDF]

open access: yes
We consider an asymptotic version of Mas-Colells theorem on the existence of pure strategy Nash equilibria in large games. Our result states that, if players payoff functions are selected from an equicontinuous family, then all sufficiently large games ...

Existence Result for Impulsive Differential Equations with Integral Boundary Conditions

open access: yesAbstract and Applied Analysis, 2013
We investigate the following differential equations: -(y[1](x))'+q(x)y(x)=λf(x,y(x)), with impulsive and integral boundary conditions -Δ(y[1](xi))=Ii(y(xi)), i=1,2,…,m, y(0)-ay[1](0)=∫0ωg0(s)y(s)ds, y(ω)-by[1](ω)=∫0ωg1(s)y(s)ds, where y[1](x)=p(x)y'(x ...

An Existence Result for Second-Order Impulsive Differential Equations with Nonlocal Conditions

open access: yesDiscrete Dynamics in Nature and Society, 2010
The Leray-Schauder alternative is used to investigate the existence of solutions for second-order impulsive differential equations with nonlocal conditions in Banach spaces. The results improve some recent results.
