New constructions relating Real and Complex Contact Structure

摘要

We establish new connections between real and complex contact geometry via embeddings of 3-manifolds into \C3\C^3. We introduce a new \emph{contact wedge} construction combining two transverse real contact structures to make a new \emph{complex contact} structure, subject to obstructions measured by the Nijenhuis tensor and Dolbeault cohomology. Dually, we form a \emph{hedge} construction which extracts real contact structures from complex ones. Applying these tools, we prove that \C3\C^3 admits uncountably many complex contact structures.
