Global $\bar\partial_{\bold M}$-homotopy with $C^k$ estimates for a family of compact, regular q-pseudoconcave CR manifolds

Abstract

Let ${\bold M}_0$ be a compact, regular q-pseudoconcave compact CR submanifold of a complex manifold ${\bold G}$ and ${\cal B}$ - a holomorphic vector bundle on ${\bold G}$ such that $\dim H^r({\bold M}_0, {\cal B}\big|_{\bold M})=0$ for some fixed $r<q$. We prove a global homotopy formula with $C^k$ estimates for $r$-cohomology of ${\cal B}$ on arbitrary CR submanifold ${\bold M}$ close enough to ${\bold M}_0$.
