Abstract:The existence of infinitely many solutions of the following Dirichlet problem for p-mean curvature operator: 
$$left{ begin{gathered}  div((1  +  left| {nabla u} right|^2 )^{frac{{P - 2}}{2}} nabla u) = f(x,u), x in Omega , hfill   u  in  W_0^{1P} (Omega ), hfill  end{gathered}  right.$$
is considered, where Θ is a bounded domain in R n (n>p>1) with smooth boundary ∂Θ. Under some natural conditions together with some conditions weaker than (AR) condition, we prove that the above problem has infinitely many solutions by a symmetric version of the Mountain Pass Theorem if 
$$frac{{f(x,u)}}{{left| u right|^{p - 2} u}} to  + infty  as u to  infty $$
