Contact geometry is a branch of differential geometry that deals with contact manifolds, which are odd-dimensional manifolds equipped with a special kind of geometrical structure called a contact structure. This structure can be thought of as a geometric way of capturing certain properties of systems that exhibit a notion of "direction," and it is closely related to the study of dynamical systems and thermodynamics.
