Avoiding maximal parabolic subgroups of S_k [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2000
We find an explicit expression for the generating function of the number of permutations in S_n avoiding a subgroup of S_k generated by all but one simple transpositions.

Parabolic subgroups of Garside groups

open access: yesJournal of Algebra, 2007
A Garside monoid is a cancellative monoid with a finite lattice generating set; a Garside group is the group of fractions of a Garside monoid. The family of Garside groups contains the Artin-Tits groups of spherical type. We generalise the well-known notion of a parabolic subgroup of an Artin-Tits group into that of a parabolic subgroup of a Garside ...

Three-Dimensional Transesophageal Echocardiographic Vena Contracta Area for Grading Mitral Regurgitation: Severity Cut-offs From a Prospective Tunisian Cohort. [PDF]

open access: yesEchocardiography
Three‐dimensional vena contracta area (VCA) measured by transoesophageal echocardiography enables precise accurate quantification of mitral regurgitation severity. In a Tunisian cohort, 3D VCA showed strong correlations with conventional 2D indices and excellent diagnostic performance for severe MR, supporting its use particularly in rheumatic mitral ...

COMPACT ORBITS OF PARABOLIC SUBGROUPS [PDF]

open access: yesNagoya Mathematical Journal, 2021
AbstractWe study the action of a real reductive group G on a real submanifold X of a Kähler manifold Z. We suppose that the action of a compact connected Lie group U with Lie algebra $\mathfrak {u}$ extends holomorphically to an action of the complexified group $U^{\mathbb {C}}$ and that the U-action on Z is Hamiltonian. If $G\subset U^{\mathbb {C}

Parabolic double cosets in Coxeter groups [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
Parabolic subgroups WI of Coxeter systems (W,S) and their ordinary and double cosets W/WI and WI\W/WJ appear in many contexts in combinatorics and Lie theory, including the geometry and topology of generalized flag varieties and the symmetry groups of ...

Curve graphs for Artin–Tits groups of type B, A∼ and C∼ are hyperbolic

open access: yesTransactions of the London Mathematical Society, 2021
The graph of irreducible parabolic subgroups is a combinatorial object associated to an Artin–Tits group A defined so as to coincide with the curve graph of the (n+1)‐times punctured disk when A is Artin's braid group on (n+1) strands.
