Of course, this cannot hold for arbitrary metrics (for example if M is simply connected). This problem was stated as a conjecture in [BK] in the case where M is a closed surface and g1

WebDe nition 1 (Length Spectrum). Given a domain , the length spectrum of is given by the set of lengths of its periodic orbits, counted with multiplicity: L:= Nflengths of closed geodesics in g[N‘(@); where ‘(@) denotes the length of the boundary.
