A well-known result of Benjamini, Lyons, Peres, and Schramm states that if G is a finitely generated Cayley graph group Γ , then amenable only admits -invariant random spanning tree with at most two ends. We show this equivalent to the existence double ray in power .

The non-split extension group $overline{G} = 5^3{^.}L(3,5)$ is a subgroup of order 46500000 and of index 1113229656 in Ly. The group $overline{G}$ in turn has L(3,5) and $5^2{:}2.A_5$ as inertia factors. The group $5^2{:}2.A_5$ is of order 3 000 and is of index 124 in L(3,5). The aim of this paper is to compute the Fischer-Clifford matrices of $overline{G}$, which together with associated parti...

The underlying thesis of this paper is that crime control policy is politically constructed. In developing our thesis and its implications, we depart from much of the conventional wisdom in three basic ways. First, in demonstrating the political derivations of crime control policy we reveal how, why, and to what extent criminological knowledge is marginalized in the policymaking process. Second...
