"Thirteen ways of looking at a topological group" (January 8, 2007 at the AWM Workshop, Joint Mathematics Meetings in New Orleans)

·        The title of this talk is taken from Wallace Stevens' poem, "Thirteen Ways of Looking at a Blackbird." 

·        I've wrote a parody of this poem about the thirteen ways of looking at a topological group, which can be found here.)
