A recent description of the relation between time slicing
and Ito versus Stratonovich calculus can be found in
H. Nakazato, K. Okano, L. Schülke, and Y. Yamanaka,
Nucl. Phys. B 346, 611 (1990).
Stochastic differential equations in curved spaces are developed in
K.D. Elworthy, Stochastic differential equations on manifolds,
Cambridge Univ. Press, 1982;

Springer, Berlin 1989.

In the holonomic case,
