Quotients et extensions de groupes de reflexions complexes

备注：: 29 pages, French

英文摘要：

We give a geometric description of a certain class of epimorphisms between complex reflection groups. We classify these epimorphisms, which can be interpreted as ``morphisms'' between the diagrams symbolizing standard presentations by generators and relations for complex reflection groups and their braid groups.

Représentations de réflexion de groupes de Coxeter Première partie: le cas irréductible

In this work we study representations of certain Coxeter groups to obtain some properties of the corresponding reflection groups.

Une (nouvelle ?) construction du groupe de réflexion complexe $G_{31}$

In Shephard-Todd classification of finite (complex) reflection groups, the group $G_{31}$ appears to be the unique one in rank 4 of order 46080. We provide here an elementary construction starting from the Weyl group of type $B_6$.

Représentations de réflexion de groupes de Coxeter Sixième partie: le cas réductible; exemples en rang trois

In this sixth part we study rank $3$ reflection groups not well generated: $G(2r,r,2)$, $G_{12}$, $G_{13}$ and $G_{22}$. We start from a reflection representation of a rank $3$ Coxeter group and we show that we can obtain in this manner affine Coxeter groups whose linear part is one of the preceding groups.

Représentations de réflexion de groupes de Coxeter Deuxième partie: outils pour des exemples

This part is made of three sections. In the first section we study the family of polynomials whose roots are 4cos2 kπ, (n \geqslant 3,1 \leqslant k < \frac{n}{2}). We obtain n2 in this manner a family of orthogonal polynomials. This will permit us to study in details all the examples which follow. In the second section, we give technical formulae in order noto repeat calculations. In the third section,we give applications, first when the field K is a sub-field of R (presentations of W(H3) and W(H4)) then in the complex case (study of the complex reflection group G(p, p, n), G24 and G27).

Groupes de réflexion, géométrie du discriminant et partitions non-croisées

Reflection groups, geometry of the discriminant and noncrossing partitions. When W is a well-generated complex reflection group, the noncrossing partition lattice NCP_W of type W is a very rich combinatorial object, extending the notion of noncrossing partitions of an n-gon. This structure appears in several algebraic setups (dual braid monoid, cluster algebras...). Many combinatorial properties of NCP_W are proved case-by-case, using the classification of reflection groups. It is the case for Chapoton's formula, expressing the number of multichains of a given length in the lattice NCP_W, in t…

Simplicite de groupes d'automorphismes d'espaces a courbure negative

We prove that numerous negatively curved simply connected locally compact polyhedral complexes, admitting a discrete cocompact group of automorphisms, have automorphism groups which are locally compact, uncountable, non linear and virtually simple. Examples include hyperbolic buildings, Cayley graphs of word hyperbolic Coxeter systems, and generalizations of cubical complexes, that we call even polyhedral complexes. We use tools introduced by Tits in the case of automorphism groups of trees, and Davis-Moussong's geometric realisation of Coxeter systems.

Approximation forte pour les espaces homogènes de groupes semisimples sur le corps des fonctions d'une courbe algébrique complexe

Let K be the function field of a curve over the complex field. Let X be a homogeneous space of a semisimple linear algebraic group. Strong approximation holds for X outside any finite nonempty set of places of K. Strong approximation fails for tori over K.

Morphismes injectifs entre groupes d'Artin-Tits

We construct a family of morphisms between Artin-Tits groups which generalise the ones constructed by J. Crisp in [Injective maps between Artin groups, Proceedings of the Special Year in Geometric Group Theory, Berlin, (1999), 119 -- 138]. We show that their restrictions to the positive Artin monoids respect normal forms, and that for Artin-Tits groups of type FC, these morphisms are injective. The proof of the second result uses the Deligne Complex, and the normal cube paths constructed in [G. Niblo and L. Reeves, The geometry of cube complexes and the complexity of their fundamental groups, …
