Four people have volunteered to speak about specific topics. The dates of their lectures will be announced later.
Harper Wells will speak about the problem of the existence of a model companion of the the theory $T_\sigma$ of models of a theory $T$ with a specified automorphism.
Yuki Takahashi will speak about supersimplicity in ACFA.
Jordan Brown and Ronan O’Gorman will speak about the trichotomy theorem for ACFA.
