Hrushovski constructions - specifically, particular classes of 2-sparse graphs - behave differently to previous classes studied in the context of the KPT correspondence, as first shown in papers of Evans, Hubi?ka and Ne?et?il (2019, 2021). We will discuss results from these papers, including how to find Ramsey expansions of classes of sparse graphs via a Ramsey theorem for classes of structures with set-valued functions. We will also discuss some new results from the speaker's PhD thesis (supervised by Evans), extending results from the above papers.
