I see that the SR variety of the simplicial complex consisting of three isolated points is exactly the cone, three coordinate axes. But if you have the 1-simplex, it corresponds to the $A^2$. In how far is this a cone? If you draw the 1-simplex as connecting $(1,0)$ and $(0,1)$, the cone is just the first and the third quadrant of $A^2$, right? Can one get the non-homogeneous SR ring out of the homogeneous one? How? Thanks. | |
