Abstract.
We define a generalized
pseudohermitian structure on an almost CR manifold
as a pair (h,P),
where h is a positive definite fiber metric h on
compatible with J, and
is a smooth projector such
that
.
We show that to each generalized pseudohermitian
structure one can associate a canonical linear connection
on the holomorphic bundle
which is invariant
under equivalence. This fact allows us to solve the equivalence problem in the case where
is a kind 2 distribution. We study the curvature of the canonical connection, especially for the classes of standard homogeneous
manifolds and 3-Sasakian manifolds. The
basic formulas for isopseudohermitian immersions are also
obtained in the attempt to enlarge the theory of pseudohermitian immersions between strongly pseudoconvex pseudohermitian manifolds of hypersurface type.
