Subelliptic Spin_C Dirac operators, II Basic Estimates
Abstract
We assume that the manifold with boundary, X, has a Spin_C-structure with spinor bundle S. Along the boundary, this structure agrees with the structure defined by an infinite order integrable almost complex structure and the metric is Kahler. The induced CR-structure on bX is integrable and either strictly pseudoconvex or strictly pseudoconcave. We assume that E->X is a complex vector bundle, which has an infinite order integrable complex structure along bX, compatible with that defined along bX. In this paper use boundary layer methods to prove subelliptic estimates for the twisted Spin_C- Dirac operator acting on sections on S\otimes E. We use boundary conditions that are modifications of the classical dbar-Neumann condition. These results are proved by using the extended Heisenberg calculus.
