Some results on NIP groups and their Ellis groups
Atticus Stonestrom
The paper develops a notion of piecewise (strong) f‑generic definable sets in NIP groups, shows they form an ideal, and uses this to obtain new results on the size and structure of…

An arithmetic algebraic regularity lemma
Anand Pillay, Atticus Stonestrom
We give an 'arithmetic regularity lemma' for groups definable in finite fields, analogous to Tao's 'algebraic regularity lemma' for graphs definable in finite fields. More specific…

On f-generic types in NIP groups
Atticus Stonestrom
Recall that a definable group is `definably amenable' if it admits a translation-invariant Keisler measure. We prove a combinatorial characterization of definable amenability for g…
