DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCSD_NTS/19/
 ">Topological modular forms for number theorists</a>\nby Paul Van Koughnet
 t (Purdue) as part of UCSD number theory seminar\n\nLecture held in normal
 ly APM 7321\, currently online.\n\nAbstract\nThis will be a mainly exposit
 ory talk about some recent applications of number theory to topology. The 
 crux of these applications is the construction of a cohomology theory call
 ed topological modular forms (TMF) out of the moduli of elliptic curves. I
 'll explain what TMF is\, what we have been doing with it\, and what we'd 
 still like to know\; I'll also discuss more recent attempts to extend the 
 theory using level structures\, higher-dimensional abelian varieties\, and
  K3 surfaces. Time permitting\, I'll talk about my work with Dominic Culve
 r on some partial number-theoretic interpretations of TMF co-operations.\n
 \nI'll give a pre-talk.\n
