|Title:||Existence and asymptotic behavior for elliptic equations with singular anisotropic potentials|
|Abstract:||We study the equation Delta u + u vertical bar u vertical bar(P-1) + V(x)u + (x) = 0 in R(n), where n >= 3 and p > n/(n - 2). The forcing term f and the potential V can be singular at zero, change sign and decay polynomially at infinity. We can consider anisotropic potentials of form h(x)vertical bar x vertical bar(-2) where h is not purely angular. We obtain solutions u which blow up at the origin and do not belong to any Lebesgue space L(r). Also, u is positive and radial, in case f and V are. Asymptotic stability properties of solutions, their behavior near the singularity, and decay are addressed. (c) 2010 Published by Elsevier Inc.|
