Cichon's diagram and large cardinals

Andrew Brooke-Taylor, University of Leeds. Part of the pure mathematics postgraduate logic seminar series.

I will introduce Cichon's diagram, which shows the relationships between 10 uncountable cardinals that are at most the cardinality c of the reals, but may be strictly less than c. Then I'll talk about some recent joint work generalising the definitions to other cardinals.
