Special connections in almost paracontact metric geometry

‎Two types of properties for linear connections (natural and almost paracontact metric) are discussed in almost paracontact metric geometry with respect to four linear connections‎: ‎Levi-Civita‎, ‎canonical (Zam\-ko\-voy)‎, ‎Golab and generalized dual‎. ‎Their relationship is also a\-na\-lyzed with a special view towards their curvature‎. ‎The particular case of an almost para-cosymplectic manifold gives a major simplification in computations since the paracontact form is closed‎.
