Abstract: In this note, we study an invariant associated to the zeros of the moment mapgenerated by an action form, the infinitesimal index. This construction will beused to study the compactly supported equivariant cohomology of the zeros ofthe moment map and to give formulas for the multiplicity index map of atransversally elliptic operator.
