In poetry:

Dem Führer aus der Hand, - im Augenblick
Da gleitet wohl im Sturz die teure Waffe
Bemerkt er den Verlust, im Kugelregen
Kehrt er gelassen an den Ort zurück.

In science:

We have the semi-direct product Waff = W (cid:110) ˇQ acting on t, with ˇQ acting as translations and the Weyl group as point symmetries.
Cubature formulae for orthogonal polynomials in terms of elements of finite order of compact simple Lie groups
Waff is called the affine Weyl group. A fundamental region F for t under the action of Waff can be given as follows.
Cubature formulae for orthogonal polynomials in terms of elements of finite order of compact simple Lie groups
There is a similar length function for Waff The action of Waff on F tiles the entire space t with copies of F, and in this way F serves as a fundamental domain for it.
Cubature formulae for orthogonal polynomials in terms of elements of finite order of compact simple Lie groups
In particular, all x ∈ F ◦ have trivial stabilizer in Waff .
Cubature formulae for orthogonal polynomials in terms of elements of finite order of compact simple Lie groups
Although each element of W and each element of Waff is a product of reflections, it is not uniquely so.
Cubature formulae for orthogonal polynomials in terms of elements of finite order of compact simple Lie groups
Note that none of the reflecting hyperplanes (5) or (6), nor indeed any reflecting hyperplane of Waff, meets the interior F ◦ of F and so Sρ (x) is never 0 in F ◦ .
Cubature formulae for orthogonal polynomials in terms of elements of finite order of compact simple Lie groups
Lemma 3.1. [Hum] The affine Weyl group Waff is the semidirect product W ⋉ L∨ of the usual Weyl group W and the coroot lattice L∨ .
Alcoved Polytopes II
Lemma 3.2. [Hum] The affine Weyl group Waff acts simply transitively on the col lection A of al l alcoves.
Alcoved Polytopes II
Lemma 3.2 implies that all alcoves are obtained from A◦ by the action of Waff .
Alcoved Polytopes II
The closure of the fundamental alcove A◦ is a fundamental domain of Waff .
Alcoved Polytopes II
Condition 2 follows immediately from translating the action of the simple generators of Waff on alcoves.
Alcoved Polytopes II
Let us define the equivalence relation “∼” on the affine Weyl group Waff by u ∼ w if and only if u(A◦ ) = w(A◦ ) + λ, for some λ ∈ Λ∨, where u, w ∈ Waff .
Alcoved Polytopes II
Actually, C is a subgroup in W and Caff is a subgroup in Waff .
Alcoved Polytopes II
Equivalence classes of elements of the Weyl group (respectively, the affine Weyl group) with respect to the relation “∼” are exactly cosets in W/C (respectively, Waff /Caff ).
