Abstract

The paper is concerned with the equation -Δhu = f(u) on Sd where Δh denotes the Laplace-Beltrami operator on the standard unit sphere (Sd, h), while the continuous nonlinearity f : ℝ → ℝ oscillates either at zero or at infinity having an asymptotically critical growth in the Sobolev sense. In both cases, by using a group-theoretical argument and an appropriate variational approach, we establish the existence of [d/2] + (-1)d+1 - 1 sequences of sign-changing weak solutions in H12(Sd) whose elements in different sequences are mutually symmetrically distinct whenever f has certain symmetry and d ≥ 5. Although we are dealing with a smooth problem, we are forced to use a non-smooth version of the principle of symmetric criticality (see Kobayashi-Ôtani, J. Funct. Anal. 214 (2004), 428-449). The L - and H12-asymptotic behaviour of the sequences of solutions are also fully characterized.
