A note on nonexistence of radial solutions to semilinear elliptic inequations

We study the nonexistence result of radial solutions to -Deltau + c u/\x\(2) + \x\(sigma)\u\(q)u less than or equal to 0 posed in B or in B \ {0} where B is the unit ball centered at the origin in R-N, N greater than or equal to 3. Moreover, we give a complete classification of radial solutions to the problem -Deltau + c u/\x\(2) + \x\(sigma)\u\(q)u = 0. In particular we prove that the latter has exactly one family of radial solutions.
