  Let $X$ be a toric variety. Rationally Borel-Moore homology of $X$ is
isomorphic to the homology of the Koszul complex $A^T_*(X)\otimes \Lambda^\x
M$, where $A^T_*(X)$ is the equivariant Chow group and $M$ is the character
group of $T$. Moreover, the same holds for coefficients which are the integers
with certain primes inverted.
