# Set Theory E-Seminar: Jing Zhang (BIU) - Transformations of the transfinite plane

11:00am to 1:00pm

## Location:

E-seminar Zoom meeting ID 243-676-331

Joint E-seminar of Bar-Ilan University and the Hebrew University

**Title**: Transformations of the transfinite plane

**Abstract**: We discuss the existence of certain transformation functions turning pairs of ordinals into triples (or pairs) of ordinals, that allows reductions of complicated Ramsey theoretic problems into simpler ones. We will focus on the existence of various kinds of strong colorings. The basic technique is Todorcevic's walks on ordinals. Joint work with Assaf Rinot.
