[Theory] Colloquium: Julia Wolf (Cambridge)

[Alexander Razborov]

This math talk (March 2, 3pm, Eck 202) may be of interest to some. Julia is also talking at our Theory seminar on March 8, I will send a separate announcement about that one.

> Abstract:
> 
> In this talk we will come at this question from two
> different angles: first, from the viewpoint of model theory, a subject
> in which for nearly half a century the notion of stability has played
> a central role in describing tame behaviour; secondly, from the
> perspective of combinatorics, where so-called regularity
> decompositions have enjoyed a similar level of prominence in a range
> of finitary settings, with remarkable applications.
> 
> In recent years, these two fundamental notions have been shown to
> interact in interesting ways. In particular, it has been shown that
> mathematical objects that are stable in the model-theoretic sense
> admit particularly well-behaved regularity decompositions. In this
> talk we will explore this fruitful interplay in the context of both
> finite graphs and subsets of abelian groups.
> 
> To the extent that time permits, I will go on to describe recent joint
> work with Caroline Terry (The Ohio State University), in which we
> develop a higher-arity generalisation of stability that implies (and
> in some cases characterises) the existence of particularly pleasant
> higher-order regularity decompositions.
