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 ...

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.

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 ...

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.

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 ...
