Automorphism groups of countable stable structures

by Paolini and Shelah. [PaSh:1107]

For every countable structure M we construct an aleph_0-stable countable structure N such that Aut(M) and Aut(N) are topologically isomorphic. This shows that it is impossible to detect any form of stability of a countable structure M from the topological properties of the Polish group Aut(M) .
