DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SF-and-nt/9/
 ">Two-dimensional gauge theories\, intersection numbers and special functi
 ons</a>\nby Debashis Ghoshal (School of Physical Sciences\, JNU) as part o
 f Special Functions and Number Theory seminar\n\n\nAbstract\nThe partition
  function of two dimensional Yang-Mills theory contains a wealth of inform
 ation about the moduli space of connections on surfaces. We study this pro
 blem on a special class of surfaces of infinite genus\, which are construc
 ted recursively. While the results are suggestive of an underlying geometr
 ical structure\, we use it as a prop to efficiently compute results for fi
 nite genus surfaces. Riemann zeta function\, confluent hypergeometric func
 tion and its truncations show up in explicit computations for the gauge gr
 oup SU(2). Much of the corresponding results are open for other groups.\n
