Abstract or Additional Information

I will give a gentle introduction to the `small cardinals', $\mathfrak{b}$, $\mathfrak{d}$, $\mathfrak{p}$ and $\mathfrak{t}$, focussing on topological interpretations and applications.

This is in preparation for Malliaris' Appalachian Set Theory Workshop on `Cofinality spectrum problems: $\mathfrak{p}$, $\mathfrak{t}$, and model theory', which will take place on November 5. See this page for further details.
