 Knot Invariants in Relation to Statistical Mechanics and Quantum Field The
 ory</a>\nby Louis Kaufmann (UI Chicago) as part of Göttingen Colloquium o
 f the Research Traininig Group "Fourier Analysis and Spectral Theory"\n\n\
 nAbstract\nThis talk will explain a construction due to the speaker (the b
 racket polynomial) that is a state summation model for the Jones polynomia
 l. This state summation is part of a larger structure that includes the Po
 tts model in statistical mechanics and it has a quantum field theoretic in
 terpretation via the functional integral approach of Edward Witten. We wil
 l explain the basics of these relationships without any prior knowledge re
 quired of these areas of mathematics and physics.\n

 Rationality of Poincaré series at 0 for surfaces</a>\nby Viet Ngyuen Dang
  (Lyon) as part of Göttingen Colloquium of the Research Traininig Group "
 Fourier Analysis and Spectral Theory"\n\n\nAbstract\nThis is joint work wi
 th Gabriel Rivière. On a surface with negative curvature\, we show that P
 oincaré series counting geodesic arcs orthogonal to certain curves have m
 eromorphic continuation to the complex plane. When these curves are homolo
 gically trivial geodesics\, we show there are no poles at 0 and rationalit
 y of the value at 0 by interpreting this value as a linking number for Leg
 endrian knots.\n
