Title: Compact metrizable structures and classification problems II

Abstract:

We consider compact metrizable spaces with equipped with closed relations. Two such structures are considered equivalent when there is a homeomorphism between their domains that respects the relational structure. By representing other classes of objects as compact structures, we establish bounds for classification problems in Borel reducibility. Portions of this talk are based on joint work with C. Rosendal.
