Oct 4, 2017 at 12:08 comment added Ali Taghavi This is some how similar to the following fact(in the case of 2-sphere): If we identify $S^2$ with the space of projectiions of $M_2(\mathbb{C})$ then every vector field on $S^2$ can be written in the form $\dot X= [A,X]=AX-XA$ for some antisymmetric 2x2 matrix A. I learned this fact in page 13 of the book Non commutative Geometry by Alain Connes(When he was interpreting the consequence of the Gauss Bonnet theorem in terms of cyclic cocycles)
