+==== non-unimodular case? quotient? ====
+How to describe the upstair space $(t-1)^2 = uv$, and $(t-1) = (uv)^2$, and $t^2 - 1 = uv$? Maybe the first one is more serious. You can deform it, to $(t-1)(t-1-\epsilon)=uv$, or you can resolve it. I guess, we want to deform it.
+suppose we have several copies of this space, and we want to do multiplicative reduction, what do we do? We
+consider certain product, like $t_1 t_2 t_3^2 = b$ (say we want to do weighted proj space), and then we quotient out the fiber by something.
+Downstairs space, what do we do with the quotient step?
