General covariant derivatives for general connections
In this paper we introduce the general covariant derivatives of vertical-valued tensor fields with respect to a general connection on a fibered manifold and a classical connection on the base. We prove that the general<...

An outline of covariant quantum mechanics
We outline a generally covariant formulation of quantum mechanics for a scalar particle in a curved spacetime, which is fibred over absolute time and is equipped with given spacelike metric, gravitational field and electromagnetic f...

Uniqueness results by covariance in covariant quantum mechanics
We show that the only requirement of general covariance essentially determines the quantum operators associated with a classical quantisable function and the Schr"odinger operator. Our framework is the covariant quantum mec...
