Ranking Friends ∗
We investigate the scope for cooperation within a community engaged in repeated reciprocal interactions. Players seek the help of others and approach them sequentially according to some fixed order, that is, a ranking profile. We study the ranking profiles that correspond to the social structures that are most effective in sustaining cooperation in equilibrium, that is, social structures that s...
متن کاملA fast algorithm for identifying Friends-of-Friends halos
We describe a simple and fast algorithm for identifying friends-of-friends clusters and prove its correctness. The algorithm avoids unnecessary expensive neighbor queries, uses minimal memory overhead, and rejects slowdown in high over-density regions. We define our algorithm formally based on pair enumeration, a problem that has been heavily studied in fast 2-point correlation codes and our re...

متن کاملScalar Glueballs and Friends
The f0(1500) is identified in three glueball favoured production mechanisms: pp̄ annihilation, ψ → γf0 and Central Production. The production rate for glueballs in ψ → γG has been quantified and the f0(1500) is found to be consistent with a glueball qq̄ mixture. We illustrate a remarkable property of central production where kinematic cuts appear to make a systematic separation between glueballs ...
متن کاملIkp and Friends
There has been increasing interest in intuitionistic methods over the years. Still, there has been relatively little work on intuitionistic set theory, and most of that has been on intuitionistic ZF. This investigation is about intuitionistic admissibility and theories of similar strength. There are several more particular goals for this paper. One is just to get some more Kripke models of vari...
