摘要

We describe the Chow ring with rational coefficients of (M) over bar (0,1)(P-n, d) as the subring of invariants of a ring B*((M) over bar (0,1)(P-n, d); Q), relative to the action of the group of symmetries S-d. We compute B*((M) over bar (0,1)(P-n, d); Q) by following a sequence of intermediate spaces for (M) over bar (0,1)(P-n, d).
