Ziv Shami
We prove that a countable simple unidimensional theory that eliminates hyperimaginaries is supersimple. This solves a problem of Shelah in the more general context of simple theori…

Rigid aleph_epsilon-saturated models of superstable theories
Ziv Shami, Saharon Shelah
In a countable superstable NDOP theory, the existence of a rigid aleph_epsilon-saturated model implies the existence of 2^lambda rigid aleph_epsilon-saturated models of power lambd…
