Abstract or Description

Abstract: "A homogeneous family of subsets over a given set is one with a very 'rich' automorphism group. We prove the existence of a bi-universal element in the class of homogeneous families over a given infinite set and give an explicit construction of 2²[superscript N]⁰ isomorphism types of homogeneous families over a countable set."
