## Abstract Refining the notion of an ideal triangulation of a compact three‐manifold, we provide in this paper a combinatorial presentation of the set of pairs (__M__,__α__), where __M__ is a three‐manifold and __α__ is a collection of properly embedded arcs. We also show that certain well‐underst

The asymptotic behavior of the flow for a system of the Navier Stokes type is investigated. In the considered model, the viscous part of the stress tensor is generally a nonlinear function of the symmetric part of the velocity gradient. Provided that the function describing this dependence satisfies
## Abstract For a small deformation Φ of a 3‐dimensional pseudoconvex embeddable CR‐structure of finite type, we prove that Φ defines an embeddable CR‐structure if and only if the Szegö projection from ker $ ^{\rm \Phi} {\bar \partial} \_{b} $ to ker $ {\bar \partial} \_{b} $ is a Fredholm operator
