Overgroups of the Automorphism Group of the Rado Graph

Combinatorics 2012-05-17 v1 Logic

Abstract

We are interested in overgroups of the automorphism group of the Rado graph. One class of such overgroups is completely understood; this is the class of reducts. In this article we tie recent work on various other natural overgroups, in particular establishing group connections between them and the reducts.
