摘要：

For an affine toric variety SpecoATHORN, we give a convex geometric interpretation of the Gerstenhaber product HH2(A) x HH2(A) -> HH3(A) between the Hochschild cohomology groups. In particular, our construction also generalizes the known results about the cup product T-A(1) x T-A(1) -> T-A(2).
