Meromorphic parahoric Higgs torsors and filtered Stokes G-local systems on curves

چکیده
In this paper, we consider the wild nonabelian Hodge correspondence for principal G-bundles on curves, where G is a connected complex reductive group. We establish under “very good” condition irregular type of meromorphic G-connections introduced by Boalch, and thus confirm conjecture in [9, §1.5]. first give version Kobayashi–Hitchin correspondence, which induces one-to-one between stable parahoric Higgs torsors degree zero (Dolbeault side) connections (de Rham side). Then, introducing notion stability filtered Stokes G-local systems, prove systems (Betti When G=GLn(C), main result paper reduces to that [4].

Jacobian of Meromorphic Curves*
The contact structure of two meromorphic curves gives a factorization of their jacobian. Section 1: Introduction Let J(F,G) = J(X,Y )(F,G) be the jacobian of F = F (X,Y ) and G = G(X,Y ) with respect to X and Y , i.e., let J(F,G) = FXGY − FY GX where subscripts denote partial derivatives. Here, to begin with, F and G are plane curves, i.e., polynomials in X and Y over an algebraically closed gr...
متن کاملOn Meromorphic Parameterizations of Real Algebraic Curves
A singular flat geometry may be canonically assigned to a real algebraic curve Γ; namely, via analytic continuation of unit speed parameterization of the real locus ΓR. Globally, the metric ρ = |Q| = |q(z)|dzdz̄ is given by the meromorphic quadratic differential Q on Γ induced by the standard complex form dx + dy on C = {(x, y)}. By considering basic properties of Q, we show that the condition f...
متن کاملON LOCAL HUDETZ g-ENTROPY
In this paper, a local approach to the concept of Hudetz $g$-entropy is presented. The introduced concept is stated in terms of Hudetz $g$-entropy. This representation is based on the concept of $g$-ergodic decomposition which is a result of the Choquet's representation Theorem for compact convex metrizable subsets of locally convex spaces.
متن کاملResolving G-torsors by Abelian Base Extensions
Let G be a linear algebraic group defined over a field k. We prove that, under mild assumptions on k and G, there exists a finite k-subgroup S of G such that the natural map H(K,S) −→ H(K,G) is surjective for every field extension K/k. We give two applications of this result in the case where k an algebraically closed field of characteristic zero and K/k is finitely generated. First we show tha...
متن کاملOn Parahoric Subgroups
We give the proofs of some simple facts on parahoric subgroups and on Iwahori Weyl groups used in [H], [PR] and in [R]. 2000 Mathematics Subject Classification: Primary 11E95, 20G25; Secondary 22E20. Let G be a connected reductive group over a strictly henselian discretely valued field L. Kottwitz defines in [Ko] a functorial surjective homomorphism (1) κG : G(L) −→ X (Ẑ(G)). Here I = Gal(L̄/L) ...
