Title: 
Cardinal invariants of the continuum

Abstract: 
The cardinal invariants of the continuum are cardinals which measure properties of the continuum more subtle than its cardinality. We will define some of the important ones and discuss their properties. Note: This seminar will provide some background for Mayanthe Malliaris' forthcoming Appalachian Set Theory workshop on November 5, see workshop web page for details.
