## Torsion, curvature and deflection $$d$$-tensors on $$J^1(T, M)$$.(English)Zbl 0999.53024

Some special connections and their torsion and curvature tensors on manifolds of jets are investigated and their components are calculated in coordinates. The coordinate expressions of Olver’s prolongation (lifting) of vector fields on $$T\times M$$ to $$J^1(T,M)$$ are derived as well.
