In this paper we fully describe the set of the positive and nodal (regular
and singular) radial solutions of the superlinear elliptic PDE.
= Deltau = lambdau + (u)(p-1) u in B-1. u = 0 on partial derivativeB(1). p
>1. (1)
without restriction on the range of lambda is an element of R. Here, B-1 is
the unit ball in R-N.
More precisely, in all subcritical, critical and supercritical cases, we an
alyze the possible singularities of radial solutions at the origin and the
number of bounded and unbounded solutions. The solutions will be of three d
ifferent types: bounded with a finite number of zeroes in (0, 1), singular
at the origin, still with a finite number of zeroes and singular with sign
changing oscillations at the origin. (C) 2000 Academic Press.
