Abstract

 

I'll give motivation for this topic; state some background on cross sections,
cocycles and the Parry Sullivan argument; outline the classifying invariants for
flow equivalence in the primitive and G-primitive SFT case; sketch the
proof strategy; discuss the mapping class group of an SFT (with many open
questions); and indicate the results and frontiers for understanding flow
equivalence in the sofic case.

This is taken out of joint works with Huang; M. Sullivan; and Carlsen and Eilers.
For the mapping class group, I will cite some results of Chuysurichay.
