%0 Journal Article %T Lengths of geodesics on non-orientable hyperbolic surfaces %A Paul Norbury %J Mathematics %D 2006 %I arXiv %X We give an identity involving sums of functions of lengths of simple closed geodesics, known as a McShane identity, on any non-orientable hyperbolic surface with boundary which generalises Mirzakhani's identities on orientable hyperbolic surfaces with boundary. %U http://arxiv.org/abs/math/0612128v2
