Title: Cardinal invariants above the continuum

URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html

Abstract:
I will give an overview of cardinal invariants at regular uncountable cardinals.
I outline the proof of my joint result with Shelah that $\mathfrak s_\kappa\le\mathfrak b_\kappa$ for all uncountable regular kappa.
There are lots of open questions in the area. I will end with some of them.
