Semisimple orbits of Lie algebras and card-shuffling measures on Coxeter groups

Random walk on the chambers of hyperplanes arrangements is used to define a family of card shuffling measures MW;x for a finite Coxeter group W and real x<F NaN> 6= 0.

Affine extended weak order is a lattice

Coxeter groups are equipped with a partial order known as the weak Bruhat order, such that $u \leq v$ if the inversions of $u$ are a subset of the inversions of $v$.

Building planar polygon spaces from the projective braid arrangement

The moduli space of planar polygons with generic side lengths is a smooth, closed manifold. It is known that these manifolds contain the real points of the moduli space of distinct points on the projective line as an open dense subset.

A primitive derivation and logarithmic differential forms of Coxeter arrangements

A primitive derivation and logarithmic differential forms of Coxeter arrangements
Let W be a finite irreducible real reflection group, which is a Coxeter roup. We explicitly construct a basis for the module of differential -forms with logarithmic poles along the Coxeter arrangement by sing a primitive derivation. As a consequence, we extend the Hodge iltration, indexed by nonnegative integers, into a filtration indexed by ll ...
