Homogeneous families and cardinal invariants
by
Martin Goldstern
Carnegie-Mellon University

We call an independent family F subset P(\omega) homogeneous if its automorphism group is n-transitive for every natural number n. F is rigid if its automorphism group is trivial.

I will discuss some results and open questions related to these concepts.
