Kazhdan Constants of Hyperbolic Groups ∗
Let H be an infinite hyperbolic group with Kazhdan property (T ) and let κ(H,X) denote the Kazhdan constant of H with respect to a generating set X . We prove that infX κ(H,X)= 0, where the infimum is taken over all finite generating sets of H . In particular, this gives an answer to a Lubotzky question.
متن کاملEuler-mahonian Parameters on Colored Permutation Groups
New combinatorial statistics on colored permutation groups are introduced here. We present two different generalizations of major index and descent number, one of them is combinatorial in nature and the other is algebraic. We also present Euler-Mahonian type joint distributions of our parameters.
متن کاملStatistics on the Multi-Colored Permutation Groups
We define an excedance number for the multi-colored permutation group i.e. the wreath product (Zr1 × · · · ×Zrk) o Sn and calculate its multi-distribution with some natural parameters. We also compute the multi-distribution of the parameters exc(π) and fix(π) over the sets of involutions in the multi-colored permutation group. Using this, we count the number of involutions in this group having ...
متن کاملKazhdan Constants of Group Extensions
We give bounds on Kazhdan constants of abelian extensions of (finite) groups. As a corollary, we improved known results of Kazhdan constants for some meta-abelian groups and for the relatively free group in the variety of p-groups of lower p-series of class 2. Furthermore, we calculate Kazhdan constants of the tame automorphism groups of the free nilpotent groups.
متن کاملOn the Excedance Number of Colored Permutation Groups
We generalize the results of Ksavrelof and Zeng about the multidistribution of the excedance number of Sn with some natural parameters to the colored permutation group and to the Coxeter group of type D. We define two different orders on these groups which induce two different excedance numbers. Surprisingly, in the case of the colored permutation group, we get the same generalized formulas for...
