The study of computable structures and equivalence relations lies at the intersection of computability theory, algebra and logic, and provides essential insights into the classification and decision ...

Let $R$ be a Borel equivalence relation with countable equivalence classes, on the standard Borel space $(X, \mathscr{A}, \mu)$. Let $\sigma$ be a 2-cohomology class ...

This talk will be an introduction to the field of Borel equivalence relations (also called invariant descriptive set theory). No background will be assumed. We will motivate the main object of study: ...
