Klingenberg refers in [4] the fact that the homology group of the space Λ of closed H1 curves on a manifold is isomorphic to that of the Morse complex. In this paper, we generalize the fact above and at the same time give a proof to it through cell decomposition method under a strong non degeneracy condition.
We first introduce so-called generalized Morse complex on a space X with an action of Lie group G and an invariant energy function E on X. The case of the space Λ of closed curves is obviously obtained through G = S1.
