DESCRIPTION:Title: The length spectrum of triangular surfaces.\n\nAbstract:
  The marked length spectrum of a hyperbolic surface $\Sigma$ is the set of
  pairs $(\gamma\, \ell(\gamma))$\, where $\gamma$ ranges over closed geode
 sics in $\Sigma$. In 1990\, Otal showed that this set completely determine
 s the hyperbolic metric on $\Sigma$. Furthermore\, using Selberg's trace f
 ormula\, one may obtain information about the spectrum of the Laplace oper
 ator on hyperbolic surfaces from this length spectrum. In this talk\, we w
 ill describe an algorithm that generates the length spectrum up to any len
 gth for triangular surfaces.\n\n \n\nWe will gather for teatime in the lou
 nge at 4pm after the talk.\n
