Flat G-bundles and regular strata for reductive groups
Christopher L. Bremer, Daniel S. Sage
Let LG be an algebraic loop group associated to a reductive group G. A fundamental stratum is a triple consisting of a point x in the Bruhat-Tits building of LG, a nonnegative real…
A theory of minimal K-types for flat G-bundles
Christopher L. Bremer, Daniel S. Sage
The theory of minimal K-types for p-adic reductive groups was developed in part to classify irreducible admissible representations with wild ramification. An important observation…
Generalized Serre conditions and perverse coherent sheaves
Christopher L. Bremer, Daniel S. Sage
In algebraic geometry, one often encounters the following problem: given a scheme X, find a proper birational morphism from Y to X where the geometry of Y is "nicer" than that of X…
Epsilon Factors for Meromorphic Connections and Gauss Sums
Christopher L. Bremer
Let is be vector bundle with meromorphic connection on $\proj^1/k$ for some field $k \subset \cplx$, and let be the sheaf of horizontal sections on the analytic po…
Isomonodromic deformations of connections with singularities of parahoric formal type
Christopher L. Bremer, Daniel S. Sage
In previous work, the authors have developed a geometric theory of fundamental strata to study connections on the projective line with irregular singularities of parahoric formal t…
Moduli spaces of irregular singular connections
Christopher L. Bremer, Daniel S. Sage
In the geometric version of the Langlands correspondence, irregular singular point connections play the role of Galois representations with wild ramification. In this paper, we dev…
