Lie(form, V)
form
-
expression involving differential forms relative to specific coordinates
V
name or an explicit isovector [V1,V2,...Vn]
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).
