AbstractA new version of perturbation theory is developed which produces infinitely many sign-changing critical points for uneven functionals. The abstract result is applied to the following elliptic equations with a Hardy potential and a perturbation from symmetry:-Δu-μu|x|2=f(x,u)+p(x,u) in Ω,u=0 on ∂Ωand-Δu=|u|q-2|x|su+p(x,u) in Ω,u=0 on ∂Ω,where 0<s<2,Ω is a smooth bounded domain of Rn, and p(x,u) is not odd in u. Infinitely many sign-changing solutions are obtained
