Abstract / Bemerkung
We give a combinatorial characterization of Fulton’s operational Chow cohomology groups of a complete, Q-factorial, rational T-variety of complexity one in terms of so called generalized Minkowski weights in the contraction-free case. We also describe the intersection product with Cartier invariant divisors in terms of the combinatorial data. In particular this provides a new way of computing top intersection numbers of invariant Cartier divisors combinatorially.
