DESCRIPTION:Title:
Knot Invariants in Relation to Statistical Mechanics and Quantum Field The
ory\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

DESCRIPTION:Title:
Rationality of Poincaré series at 0 for surfaces\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
