Description
|
|
•
|
This routine is part of the liesymm package and is loaded via with(liesymm) .
|
•
|
It returns the wedge degree of a differential form.
|
•
|
It is defined relative to a given coordinate system, so use of setup() may change its value.
|
•
|
As the list of coordinates fully defines the one-forms, the value of this routine is just the number of terms in the basic wedge product (that is, ).
