connection; almost complex structure; tensor field; Liouville field; canonical symplectic structure
On cotangent bundles the Liouville field, the Liouville 1-form $\varepsilon$ and the canonical symplectic structure d$\varepsilon$ exist. In this paper interactions between these objects and ${(1,1)}$-tensor fields on cotangent bundles are studied. Properties of the connections induced by the above structures are investigated.
