Canonical connections on para-Kenmotsu manifolds

In the context of para-Kenmotsu geometry properties of the φ-conjugate connections of some canonical linear connections (Levi- Civita, Schouten-van Kampen, Golab and Zamkovoy canonical paracon- tact connections) are established, underlining the relations between them and between their structure and virtual tensors. The case of projec- tively and dual-projectivel equivalent connections is also treated. In particular, it is proved that the structure tensor is invariant under dual- projective transformations.
