Semidirect product decomposition of Coxeter groups
Let (W,S) be a Coxeter system, let S = I ∪ J be a partition of S such that no element of I is conjugate to an element of J , let J̃ be the set of WI -conjugates of elements of J and let W̃ be the subgroup of W generated by J̃ . We show that W = W̃ ⋊WI and that J̃ is the canonical set of Coxeter generators of the reflection subgroup W̃ of W . We also provide algebraic and geometric conditions for an e...
متن کاملOn generalized semidirect product of association schemes
In this paper, we introduce a new product operation of association schemes in order to generalize the notion of semidirect products and wreath product. We then show that our construction covers some association schemes which are neither wreath products nor semidirect products of two given association schemes.
متن کاملWigner Functions for a Class of Semidirect Product Groups
Following a general method proposed earlier, we construct here Wigner functions defined on coadjoint orbits of a class of semidirect product groups. The groups in question are such that their unitary duals consist purely of representations from the discrete series and each unitary irreducible representation is associated with a coadjoint orbit. The set of all coadjoint orbits (hence UIRs) is fi...
متن کاملThe Landau^Lifshitz Equation by Semidirect Product Reduction
The Landau^Lifshitz equation is derived as the reduction of a geodesic £ow on the group of maps into the rotation group. Passing the symmetries of spatial isotropy to the reduced space is an example of semidirect product reduction by stages. Mathematics Subject Classi¢cations (2000): 70H05, 35L70, 58B25. Key words: Landau^Lifshitz equations, Lie^Poisson reduction, geodesic £ow, momentum. The La...
متن کاملPublic Key Exchange Using Semidirect Product of (Semi)Groups
In this paper, we describe a brand new key exchange protocol based on a semidirect product of (semi)groups (more specifically, on extension of a (semi)group by automorphisms), and then focus on practical instances of this general idea. Our protocol can be based on any group, in particular on any non-commutative group. One of its special cases is the standard Diffie-Hellman protocol, which is ba...
