Existence and multiplicity results for some Lane–Emden elliptic systems: Subquadratic case

open access: yesAdvances in Nonlinear Analysis, 2015
We study the nonlinear elliptic system of Lane–Emden type -Δu = sgn(v) |v|p-1 in Ω, -Δv = f(x,u) in Ω, u = v = 0 on ∂Ω, where Ω is an open bounded subset of ℝN, N ≥ 2, p > 1 and f : Ω × ℝ → ℝ is a Carathéodory function satisfying suitable growth ...

The shape of charged drops over a solid surface and symmetry-breaking instabilities [PDF]

open access: yes, 2008
We study the static shape of charged drops of a conducting fluid placed over a solid substrate, surrounded by a gas, and in absence of gravitational forces.

Multiple positive solutions for quasilinear elliptic problems with sign‐changing nonlinearities

open access: yesAbstract and Applied Analysis, Volume 2004, Issue 12, Page 1047-1055, 2004., 2004
Using variational arguments, we prove some nonexistence and multiplicity results for positive solutions of a system of p‐Laplace equations of gradient form. Then we study a p‐Laplace‐type problem with nonlinear boundary conditions.

Existence and multiplicity of solutions for a quasilinear system with locally superlinear condition

open access: yesAdvances in Nonlinear Analysis, 2023
We investigate the existence and multiplicity of weak solutions for a nonlinear Kirchhoff type quasilinear elliptic system on the whole space RN{{\mathbb{R}}}^{N}. We assume that the nonlinear term satisfies the locally super-(m1,m2)\left({m}_{1},{m}_{2})

A note on the variational structure of an elliptic system involving critical Sobolev exponent

open access: yesJournal of Applied Mathematics, Volume 2003, Issue 5, Page 227-241, 2003., 2003
We consider an elliptic system involving critical growth conditions. We develop a technique of variational methods for elliptic systems. Using the well‐known results of maximum principle for systems developed by Fleckinger et al. (1995), we can find positive solutions.

Critical elliptic systems involving multiple strongly–coupled Hardy–type terms

open access: yesAdvances in Nonlinear Analysis, 2019
In this paper, we study the radially–symmetric and strictly–decreasing solutions to a system of critical elliptic equations in RN, which involves multiple critical nonlinearities and strongly–coupled Hardy– type terms.

A global compactness result with applications to a Hardy-Sobolev critical elliptic system involving coupled perturbation terms

open access: yesAdvances in Nonlinear Analysis, 2022
In this article, we study a Hardy-Sobolev critical elliptic system involving coupled perturbation terms: (0.1)−Δu+V1(x)u=η1η1+η2∣u∣η1−2u∣v∣η2∣x′∣+αα+βQ(x)∣u∣α−2u∣v∣β,−Δv+V2(x)v=η2η1+η2∣v∣η2−2v∣u∣η1∣x′∣+βα+βQ(x)∣v∣β−2v∣u∣α,\left\{\begin{array}{c}-\Delta u+

Quasilinear elliptic systems of resonant type and nonlinear eigenvalue problems

open access: yesAbstract and Applied Analysis, Volume 7, Issue 3, Page 155-167, 2002., 2002
This work is devoted to the study of a quasilinear elliptic system of resonant type. We prove the existence of infinitely many solutions of a related nonlinear eigenvalue problem. Applying an abstract minimax theorem, we obtain a solution of the quasilinear system −Δpu = Fu(x, u, v), − Δqv = F v(x, u, v), under conditions involving the first and the ...

Homogenization in elastodynamics with force term depending on time

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 10, Page 723-728, 2000., 2000
We extend the study on the homogenization problem for an elastic material containing a distributed array of gas bubbles to the case when the body force depends on time. By technically constructing an approximating sequence, we are able to show the convergence of semigroups and therefore prove the main result that such spongy material can be ...
