WebTheorem 1.2. Thick a ne Grassmannian Gr G is represented by a formally smooth and separated scheme. Sketch of Proof. Before we start, let’s recall that the functor L+G: R7!G(R[[t]]) is a pro-algebraic group, its C-points are just G(O), and ˇ: Gr G!Bun G(P1) is a L+G-torsor. It follows that Gr G is a formally smooth functor. Step 1. GL n case ...
