WebDefinition 39.4.1. Let be a scheme. A group scheme over is a pair , where is a scheme over and is a morphism of schemes over with the following property: For every scheme over the pair is a group. A morphism of group schemes over is a morphism of schemes over such that for every the induced map is a homomorphism of groups. WebTheorem 1.1 [F-S]. Let Gbe a nite group scheme over kand let Mbe a nite dimensional rational G-module. Then H (G;k) is a nitely generated k-algebra and H (G;M) is a nite H …

WebIn mathematics, a group extension is a general means of describing a group in terms of a particular normal subgroup and quotient group.If and are two groups, then is an … long term management of asthmaIn mathematics, a group scheme is a type of object from algebraic geometry equipped with a composition law. Group schemes arise naturally as symmetries of schemes, and they generalize algebraic groups, in the sense that all algebraic groups have group scheme structure, but group schemes are not … See more A group scheme is a group object in a category of schemes that has fiber products and some final object S. That is, it is an S-scheme G equipped with one of the equivalent sets of data • a … See more • The multiplicative group Gm has the punctured affine line as its underlying scheme, and as a functor, it sends an S-scheme T to the multiplicative group of invertible global … See more A group scheme G over a noetherian scheme S is finite and flat if and only if OG is a locally free OS-module of finite rank. The rank is a locally constant function on S, and is called the order of G. The order of a constant group scheme is equal to the order of the … See more • Given a group G, one can form the constant group scheme GS. As a scheme, it is a disjoint union of copies of S, and by choosing an identification of these copies with elements of G, one can define the multiplication, unit, and inverse maps by transport of … See more Suppose that G is a group scheme of finite type over a field k. Let G be the connected component of the identity, i.e., the maximal connected subgroup scheme. Then G is an extension of a finite étale group scheme by G . G has a unique maximal reduced … See more Cartier duality is a scheme-theoretic analogue of Pontryagin duality taking finite commutative group schemes to finite commutative group … See more Finite flat commutative group schemes over a perfect field k of positive characteristic p can be studied by transferring their … See more hopheads inc
