SUMMARY:An "L^2-version" of Alexander polynomial and 3-dimensional topology
LOCATION:Hill 705
DESCRIPTION:<p>The L^2-Alexander torsion is an invariant associated to a 3-manifold and
  an 1-cohomology class. This invariant is a real function with many propert
 ies similar to/generalizing the tranditional Alexander polynomial. In this 
 talk, I will first introduce L^2-invariants of 3-manifolds (e.g. L^2-betti 
 numbers, L^2-torsions) and discuss the "leading coefficient" of the L^2-Ale
 xander torsion and show its connection with sutured manifold theory.</p>
