Cano and J. M. Sanz-Serna (refer to fulltext for more details) on the global error behaviour of general one step methods in the numerical integration of a periodic orbit to the case that such a periodic orbit can be embedded into a family of periodic orbits. quadratic invariants Runge-Kutta methods Laburta Santamaría, María Pilar laburta@unizar.es Montijano, Juan I. monti@unizar.es Rández, Luis randez@unizar.es PAMM · Proc.
