- sm1.restriction(I,V,R)
-
:
It computes the restriction of I as a D-module to the set defined by R.
V is the list of variables.
When the optional variable degree=d is given, only the restrictions
from 0 to d are computed.
Note that, in case of vector input, RESTRICTION VARIABLES MUST APPEAR FIRST
in the list of variable V. We are using wbfRoots to get the roots of
b-functions, so we can use only generic weight vector for now.
- sm1.restriction(I,V,R | degree=key0)
-
: This function allows optional variables
