DESCRIPTION:Title: Poincaré series and linking of Legendrian knots.\n\nAbst
 ract: On a compact surface of variable negative curvature\, I will explain
  that the Poincar´e series associated to the geodesic arcs joining two giv
 en points has a meromorphic continuation to the whole complex plane. This 
 is achieved by using the spectral properties of the geodesic flow. Moreove
 r\, the value of Poincar´e series value at 0 is rationnal in that case and
  it can be expressed in terms of the genus of the surface by interpreting 
 it in terms of the linking of two Legendrian knots. If time permits\, I wi
 ll explain how this result extends when one considers geodesic arcs orthog
 onal to two fixed closed geodesics. This is a joint work with N.V. Dang.\n
