  • Ticket #12361 – Description

    initial v1  
    11For simplicial toric varieties, the rational cohomology ring and the ratironal Chow group are isomorphic. So if all normalizations are correct, then one should be able to do intersection computations in the cohomology ring. This patch fixes the `volume_class()` and the constructor of cohomology cycles from cones to make everything work.

     3It turns out that index_in_saturation does not work for trivial zero-size matrices, this is also fixed.
