چکیده
Let Xk be a proper irreducible separated scheme of finite type over a field k. We will also assume that Xk satisfies Serre’s S2 condition (for the sake of simplicity the reader may think that Xk is smooth or a locally complete intersection). For a noetherian scheme T over k denote XT = (Xk)×Spec(k) T and let Φ(T ) be the collection of all closed subsets Z ⊂ XT such that every point z ∈ Z has codimension ≥ 3 in its fiber over T . Fix a reductive group G over k.

متن کاملAlgebraization of bundles on non-proper schemes
We study the algebraization problem for principal bundles with reductive structure groups on a non-proper formal scheme. When the formal scheme can be compactified by adding a closed subset of codimension at least 3, we show that any such bundle admits an algebraization. For codimension 2 we provide a necessary and sufficient condition.
متن کاملRepresentations of Quantum Tori and G-bundles on Elliptic Curves
We study a BGG-type category of infinite-dimensional representations of H[W ], a semidirect product of the quantum torus with parameter q, built on the root lattice of a semisimple group G, and the Weyl group of G. Irreducible objects of our category turn out to be parametrized by semistable G-bundles on the elliptic curve C∗/qZ .
متن کاملNorm functors and effective zero cycles
We compare two known definitions for a relative family of effective zero cycles, based on traces and norms of functions, respectively. In characteristic zero we show that both definitions agree. In the general setting, we show that the norm map on functions can be expanded to a norm functor between certain categories of line bundles, therefore giving a third approach to families of zero cycles.
متن کاملConjugacy Classes in Loop Groups and G-Bundles on Elliptic Curves
Let C[[z]] be the ring of formal power series and C((z)) the field of formal Laurent power series, the field of fractions of C[[z]]. Given a complex algebraic group G, we will write G((z)) for the group of C((z))-rational points of G, thought of as a formal “loop group,” and a(z) for an element of G((z)). Let q be a fixed nonzero complex number. Define a “twisted” conjugation action of G((z)) o...
