Title: The wave trace on a flat surface with conical singularities.
Abstract: We study the contribution to the wave trace of diffractive periodic orbits on Euclidean surfaces with conical singularities. Using a new description of the propagator near the so-called geometrically diffractive rays, we are able to compute the leading term of any kind of diffractive periodic orbit.
