Almost-contact manifold
text:
In the mathematical field of differential geometry, an almost-contact structure is a certain kind of geometric structure on a smooth manifold. Such structures were introduced by Shigeo Sasaki in 1960. Precisely, given a smooth manifold M, an almost-contact structure consists of a hyperplane distribution Q, an almost-complex structure J on Q, and a vector field ξ which is transverse to Q. That is, for each point p of M, one selects a codimension-one linear subspace Q p of the tangent space T p M,
