The aim of this paper is to construct an immersion of the Drinfeld moduli schemes in a finite product of infinite Grassmannians, such that they will be locally closed subschemes of these Grassmannians which represent a kind of flag varieties. This construction is derived from two results: the first is that the moduli functor of vector bundles with an… (More)

Let G = SpecA be a linearly reductive group, and wG ∈ A ∗ be G-invariant and wG(1) = 1. We establish the harmonic analysis on G and we compute wG when G = Sln, Gln, On, Sp2n, by geometric arguments and by means of the Fourier transform. Introduction An affine k-group G = SpecA is semisimple if and only if A splits in the form A = k ×B∗ as k-algebras, where… (More)

In this paper we define k-elliptic sheaves, A-motives and t-modules over A, which are obvious generalizations of elliptic sheaves, t-motives and t-modules. Following results of [An1], [D], [LRSt], [Mu], [St],... we shall obtain the equivalence of this objects. Bearing in mind [Al] we also describe a correspondence between k-elliptic sheaves with formal… (More)

Let G = SpecA be a linearly reductive group and let wG ∈ A ∗ be the invariant integral on G. We establish the algebraic harmonic analysis on G and we compute wG when G = Sln, Gln, On, Sp2n by geometric arguments and by means of the Fourier transform. Introduction An affine k-group G = SpecA is linearly semisimple (that is, linearly reductive) if and only if… (More)

Let G = SpecA be an affine R-monoid scheme. We prove that the category of dual functors (over the category of commutative R-algebras) of G-modules is equivalent to the category of dual functors of A∗-modules. We prove that G is invariant exact if and only if A∗ = R × B∗ as R-algebras and the first projection A∗ → R is the unit of A. If M is a dual functor… (More)

In this paper we obtain the Cartier duality for k-schemes of commutative monoids functorially without providing the vector spaces of functions with a topology (as in [DGr, Exposé VIIB by P. Gabriel, 2.2.1]), generalizing a result for finite commutative algebraic groups by M. Demazure & P. Gabriel ([DG, II, §1, 2.10]). All functors we consider are functors… (More)

Let G = SpecA be an affine K-group scheme and Ã = {w ∈ A : dimK A ∗ · w · A < ∞}. Let 〈−,−〉 : A × Ã → K, 〈w, w̃〉 := tr(ww̃), be the trace form. We prove that G is linearly reductive if and only if the trace form is non-degenerate on A.
