Deformaciones isomonodrómicas a través de la teoría de Galois diferencial [PDF]

open access: yes, 2019
The text begins with a brief description of differential Galois theory from a geometrical perspective. Then, parameterized Galois theory is developed by means of prolongation of partial connections to the jet bundles.

Maps on surfaces and Galois groups [PDF]

open access: yes, 1997
A brief survey of some of the connections between maps on surfaces, permutations, Riemann surfaces, algebraic curves and Galois groups is ...

Biclosed Binary Relations and Galois Connections. [PDF]

open access: yes
Given two closure spaces (E,j) and (E',j'), a relation R inclue dans E x E' is said biclosed if every row of its matrix representation corresponds t o a closed subset of E', and every column to a closed subset of E.

Galois conections, chu mappings and bonds [PDF]

open access: yes, 2014
In this paper we characterize bonds, as defined by Wille, by employing a less rigid set of axioms thus enabling the definition of the category BOND. Since bonds generalize Chu mappings we present a faithful functor between CHU and BOND.

A Survey of Galois Theory [PDF]

open access: yes, 1995
In this paper, we will see a summary of Galois theory and some results utilized in Algebra. We state and prove the Fundamental Theorem of Galois theory and then work a few examples to show its application to the determination of lattices of groups and ...
