Darboux coordinates

We will now proceed to examples. We must start with describing the Darboux coordinates, which allow for concrete calculations.

At least locally, it is always possible to choose the coordinates on so that:

Antibracket and :        

(8)

Half-density:        

(9)

Canonical operator:        

(10)

Expansion of :        

To the leading order in the expansion in we get the Master Equation:
