Invariant distributions and holomorphic vector fields in paracontact geometry

Abstract

Having as a model the metric contact case of V. Brînzȃnescu; R. Slobodeanu, we study two similar subjects in the paracontact (metric) geometry: a) distributions that are invariant with respect to the structure endomorphism φ ; b) the class of vector fields of holomorphic type. As examples we consider both the 3 -dimensional case and the general dimensional case through a Heisenberg-type structure inspired also by contact geometry.
