Let $R$ be a ring generated by $l$ elements with stable range $r$. Assume that the group $EL_d(R)$ has Kazhdan constant $\epsilon_0>0$ for some $d > r $. We prove that there exist $\epsilon(\epsilon_0,l) >0$ and $k \in N$, s.t. for every $n \geq d$,

Constructing a mobile application in the enterprise is expensive and time consuming. On average, deploying a mobile application is estimated at one week of effort per screen. We present an evaluation of NitroGen, a platform-independent tool for const

Constructing a mobile application is expensive and time consuming. In this paper, we present NitroGen which is a platform independent tool that provides a consumable integrated set of capabilities to construct mobile solutions aiming at reducing deve

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 $p$-seri

We prove that the length of the shortest identity in a finite simple group of Lie type of rank $r$ defined over $\mathbb{F}_q$, is bounded (from above and below) by explicit polynomials in $q$ and $r$.

We prove that for any finite index subgroup Γ in SL n(ℤ), there exists k = k(n) ∈ ℕ, ϵ = ϵ(Γ) > 0, and an infinite family of finite index subgroups in Γ with a Kazhdan constant greater than ϵ with respect to a generating set of order k. O
