摘要: In this paper, involutions without fixed points on hyperbolic closed Riemann surface are discussed. For an orientable X of even genus with arbitrary Riemannian metric d admitting involution tau, it is known that min (p element X) d(p, tau(p)) bounded by a constant which depends the area X. The corresponding claim proved to be false in odd genus, and optimal for surfaces calculated 2.
