           THE UNIVERSITY OF NEW SOUTH WALES

             DEPARTMENT OF PURE MATHEMATICS

Speaker: Prof. Gerd Rudolph (University of Leipzig)

Title:   Singular reduction and quantization
         for lattice gauge models.

Date:    Tuesday, 25 May 2009
Time:    12:00 noon
Venue:   RC-4082, Red-Centre, UNSW 

Abstract:

After a short introduction to the subject I will discuss 
the following points:

-- The lattice gauge model as a Hamiltonian system with 
   symmetries

-- Singular Marsden Weinstein reduction of this system

-- Canonical quantization (including remarks on the 
   observable algebra and its representations)

-- How to include nongeneric gauge orbit strata on 
   quantum level?

-- Open problems
