Set Theory seminar - Juris Stperans (York) Universal functions, strong colourings and ideas from PID

Juris Stperans will speak about

Universal functions, strong colourings and ideas from PID

A construction of Shelah will be reformulated using the PID to provide alternative models of the failure of CH and the existence of a universal colouring of cardinality. The impact of the range of the colourings will be examined. An application to the theory of strong colourings over partitions will also be given.
