Procedure from library schubert.lib (see schubert_lib).
Usage:
ChowRing(V); V variety
Assume:
V is an abstract variety
Return:
qring
Example:
LIB "schubert.lib";
ring r = 0,(h,e),wp(1,1);
ideal rels = he,h2+e2;
int d = 2;
variety V = makeVariety(2,rels);
ChowRing(V);
==> // coefficients: QQ
==> // number of vars : 2
==> // block 1 : ordering dp
==> // : names h e
==> // block 2 : ordering C
==> // quotient ring from ideal ...
