Holomorphic Equivariant Cohomology via a Transversal Holomorphic Vector Field

In this paper an analytic proof of a generalization of a theorem of Bismut ([Bis1, Theorem 5.1]) is given, which says that, when $v$ is a transversal holomorphic vector field on a compact complex manifold $X$ with a zero point set $Y$, the embedding $j:Y\to X$ induces a natural isomorphism between the holomorphic equivariant cohomology of $X$ via $v$ with coefficients in $\xi$ and the Dolbeault cohomology of $Y$ with coefficients in $\xi {\mathrm{\mid }}_Y$, where $\xi \to X$ is a holomorphic vector bundle over $X$.
