SUMMARY: (...): Square roots of symplectic L-functions and Reidemeister tor
 sion
DESCRIPTION:: We give a purely topological formula for the square class of 
 the central value of the L-function of a symplectic representation on a cu
 rve. We also formulate a topological analogue of the statement\, in which 
 the central value of the L-function is replaced by Reidemeister torsion of
  3-manifolds. This is related to the theory of epsilon factors in number t
 heory and Meyer's signature formula in topology among other topics. We wil
 l present some of these ideas and sketch aspects of the proof. This is joi
 nt work with Akshay Venkatesh.
