Riemannian exponential and quantization
This article continues and completes our previous work [14] J. Phys. Commun. 2 (2018) 025007. First of all, we present two methods of quantization associated with a linear connection given on a differentiable manifold, one of them being the one presented in [14]. The two methods allow quantize functions that come from covariant tensor fields. The equivalence of both is demonstrated as a consequence of a remarkable property of the Riemannian exponential (Theorem 5.1) that, as far as we know, is new to the literature. On the other hand, the extension of the previously mentioned quantization to functions of a very broad type can be carried out by generalizing the method of [14] in terms of fields of distributions.
