Abstract:

This paper deals with the Neumann problem for a class of semilinear elliptic equations −u + u = |u|2−2u + μ|u|q−2u in , @u@ = |u|s−2u on @
, where 2 = 2N N−2 ,s = 2(N−1 ) N−2 , 1 < q < 2,N  3, μ > 0,  denotes the unit outward normal to boundary@. By variational method and dual fountain theorem, the existence of infinitely many solutions with negative energy is proved.

Key words: Neumann problem, semilinear elliptic equation, (PS) c condition, critical Sobolev exponent
