Let G be a compact Lie group and M a compact G manifold without boundary, i.e. a C manifold with a differentiate action of G on M. M is said to be G-cobordant to zero M <^ o 0 if there exists a compact G manifold Q with dQ = M. Note that in this case M G (the fixed point set of M) = ÔQGM G and QG are both disjoint unions of closed submanifolds (of varying dimension) of M, Q respectively. Let J>(MG, M) denote the normal bundle of M G in M; V(MG> M)->MG is a G-vector bundle in the sense of [S]. A partial converse to the statement V(MG, M) =dv(QG, Q) is given by
