Witrynait is locally factorial and H1(R,GL 1,R) is trivial. Since GK is isotropic, it contains a split torus; we need to show that G contains a split torus. By our assumption on R, Lie(G) is a trivial vector bundle, so we can Apply Theorem B, which reduces the question to the case, when G is of type (A WitrynaThe (integrally closed!) ring A = C [ X, Y, Z] / ( X Y − Z 2) satisfies Pic ( Spec ( A)) = 0 but is not factorial. A noetherian domain is factorial if and only if every prime ideal of height one is principal.
