Title: Representability for Relation Algebras
Abstract: In this season we've looked at classical representation results,
and how they can be explained as Galois correspondences between
abstract categories of orders and concrete categories of spaces.
In my talk I will discuss the representation problem for relation algebras.
These are orders with extra structure but they are not all ``representable''.
In contrast, relation algebras with quasi-projections are always representable.
This result has no clear categorical interpretation,
but I will try to clarify the structure of its construction.
