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

·
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.)
