Abstract: In this paper, by setting up a new Hilbert space H*2γ τ and the variational method, we finded energy functions for a class of second-order nonlinear non-autonomous neutral functional differential equations. Then by critical point and Z₂-group index theory, we get the sufficient condition for the existence of infinite periodic solutions for the system. Simultaneity, we put up an open question.
