Galois representations and tame Galois realizations [PDF]

open access: yes, 2009
[eng] The background of this dissertation is the inverse Galois problem. Which finite groups can occur as Galois groups of an extension of the rational field? This problem was first considered by D. Hilbert, and it still remains open.

Subgradients of algebraically convex functions: a Galois connection relating convex sets and subgradients of convex functions

open access: yes, 1993
Subgradients of convex functions have been defined in classical analysis for the Euclidean spaces. Here we describe a Galois connection between convex upsets and maximal homomorphisms (which are subgradient values), and interpret traditional results in ...

Galois Theory of Differential Equations, Algebraic Groups and Lie Algebras [PDF]

open access: yes, 1999
The Galois theory of linear differential equations is presented, including full proofs. The connection with algebraic groups and their Lie algebras is given. As an application the inverse problem of differential Galois theory is discussed. There are many

A Galois connection for valued constraint languages of infinite size

open access: yes
A Galois connection between clones and relational clones on a fixed finite domain is one of the cornerstones of the so-called algebraic approach to the computational complexity of non-uniform Constraint Satisfaction Problems (CSPs).

A Galois-Connection between Cattell’s and Szondi’s Personality Profiles

open access: yes, 2014
We propose a computable Galois-connection between, on the one hand, Cattell’s 16-Personality-Factor (16PF) Profiles, one of the most compre-hensive and widely-used personality measures for non-psychiatric popu-lations and their containing PsychEval ...

Monodromy of a Class of Logarithmic Connections on an Elliptic Curve

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
The logarithmic connections studied in the paper are direct images of regular connections on line bundles over genus-2 double covers of the elliptic curve.
