Irreducible Coxeter groups [PDF]

, 2005
We prove that a non-spherical irreducible Coxeter group is (directly) indecomposable and that a non-spherical and non-affine Coxeter group is strongly indecomposable in the sense that all its finite index subgroups are (directly) indecomposable. We prove

Special matchings and Coxeter groups [PDF]

, 2007
In the recent paper [Adv. Applied Math., 38 (2007), 210-226] it is proved that the special matchings of permutations generate a Coxeter group. In this paper we generalize this result to a class of Coxeter groups which includes many Weyl and affine Weyl ...

From Coxeter higher-spin theories to strings and tensor models

Journal of High Energy Physics, 2018
A new class of higher-spin gauge theories associated with various Coxeter groups is proposed. The emphasize is on the B p -models. The cases of B 1 and its infinite graded-symmetric product sym (×B 1)∞ correspond to the usual higher-spin theory and its ...

Zero excess and minimal length in finite coxeter groups [PDF]

Let \mathcal{W} be the set of strongly real elements of W, a Coxeter group. Then for $w \in \mathcal{W}$, $e(w)$, the excess of w, is defined by $e(w) = \min min \{l(x)+l(y) - l(w)| w = xy; x^2 = y^2 =1}$.

Rigidity phenomena and the statistical properties of group actions on $\text {CAT}(0)$ cube complexes

Forum of Mathematics, Sigma
We compare the marked length spectra of some pairs of proper and cocompact cubical actions of a nonvirtually cyclic group on $\mathrm {CAT}(0)$ cube complexes.
