چکیده
We give a method for obtaining radially symmetric solutions for the critical exponent problem ?u + a(x)u = u q + u 2 ?1 in R N u > 0 and R R N jruj 2 < 1 where, outside a ball centered at the origin, the non-negative function a is bounded from below by a positive constant ao > 0. We remark that, diierently from the literature, we do not require any conditions on a at innnity.

Abstract : We construct positive solutions of the semilinear elliptic problem ∆u + λu + up = 0 with Dirichet boundary conditions, in a bounded smooth domain Ω ⊂ RN (N ≥ 4), when the exponent p is supercritical and close enough to N+2 N−2 and the parameter λ ∈ R is small enough. As p → N+2 N−2 , the solutions have multiple blow up at finitely many points which are the critical points of a functi...
متن کاملThe Solvability of Concave-Convex Quasilinear Elliptic Systems Involving $p$-Laplacian and Critical Sobolev Exponent
In this work, we study the existence of non-trivial multiple solutions for a class of quasilinear elliptic systems equipped with concave-convex nonlinearities and critical growth terms in bounded domains. By using the variational method, especially Nehari manifold and Palais-Smale condition, we prove the existence and multiplicity results of positive solutions.
متن کاملExistence of three solutions for a class of quasilinear elliptic systems involving the $p(x)$-Laplace operator
The aim of this paper is to obtain three weak solutions for the Dirichlet quasilinear elliptic systems on a bonded domain. Our technical approach is based on the general three critical points theorem obtained by Ricceri.
متن کاملNon-negative Solutions for a Class of Radially Symmetric Non-positone Problems
We consider the existence of radially symmetric non-negative solutions for the boundary value problem -Au(x) = lf{u(x)) IMI < 1, x e RN{N > 2) u(x) = 0 ||*|| = 1 where X > 0, f(0) < 0 (non-positone), /' > 0 and / is superlinear. We establish existence of non-negative solutions for A small which extends some work of our previous paper on non-positone problems, where we considered the case N = \ ...
