Monodromy representations of braid groups and Yang-Baxter equations

Toshitake Kohno (1987)

Annales de l'institut Fourier

Similarity:

Motivated by the two dimensional conformal field theory with gauge symmetry, we shall study the monodromy of the integrable connections associated with the simple Lie algebras. This gives a series of linear representations of the braid group whose explicit form is described by solutions of the quantum Yang-Baxter equation.

On some Finite-Dimensional Representations of Artin Braid Group Върху някои крайномерни представяния на групата на Артин на плитките

Iliev, Valentin (2011)

Union of Bulgarian Mathematicians

Similarity:

Валентин В. Илиев - Авторът изучава някои хомоморфни образи G на групата на Артин на плитките върху n нишки в крайни симетрични групи. Получените пермутационни групи G са разширения на симетричната група върху n букви чрез подходяща абелева група. Разширенията G зависят от един целочислен параметър q ≥ 1 и се разцепват тогава и само тогава, когато 4 не дели q. В случая на нечетно q са намерени всички крайномерни неприводими представяния на G, а те от своя страна генерират безкрайна...

Cross ratios, surface groups, P S L ( n , 𝐑 ) and diffeomorphisms of the circle

François Labourie (2007)

Publications Mathématiques de l'IHÉS

Similarity:

This article relates representations of surface groups to cross ratios. We first identify a connected component of the space of representations into PSL(,ℝ) – known as the -– to a subset of the set of cross ratios on the boundary at infinity of the group. Similarly, we study some representations into C 1 , h ( 𝕋 ) Diff h ( 𝕋 ) associated to cross ratios and exhibit a “character variety” of these representations. We show that this character variety contains all-Hitchin components as well as the set of negatively...
