CM2Residual -- Strategy for eliminationMatrix.
Synopsis
-
- Usage:
- eliminationMatrix(..., Strategy => CM2Residual)
-
Consequences:
-
Suppose given a homogeneous ideal locally complete intersection Cohen-Macaulay of codimension 2,
-
J=(g1,..,gn)
-
, such that
-
I=(f1,..,fm)
-
is included in J and (I:J) is a residual intersection. Let H be the matrix that I=J.H. Let R be the matrix of the first syzygies of J. This function computes an elimination matrix corresponding to the residual resultant over V(I) over V(J).
