Lie(form, V)

Parameters

form

-

expression involving differential forms relative to specific coordinates

V

-

name or an explicit isovector [V1,V2,...Vn]

Description

• 

The Lie derivative of the differential form form is constructed with respect to V1,...,Vn where n is the number of coordinates.

• 

This routine is part of the liesymm package and is loaded via with(liesymm).
