But, in fact, the quantity turns up in the original papers by Ito himself on this topic (pg. 2), as the "drift coefficient" (in modern terminology) of the SDE for Brownian motion. | |

Jul 3, 2017 at 21:10 | comment | added | Thomas Richard | I am not sure this is what you are looking for but I don't see this $\mu^l$ as a drift term. The thing is that $\mu^l$ and $g^{ij}\partial_{ij}$ are not well defined (they depend on your particular coordinate system) while the laplace beltrami operator $g^{ij}\partial_{ij}+\mu^l\partial_l$ is a geometric object. | |
