Rández, Luis Approximate preservation of quadratic invariants by explicit Runge-Kutta methods quadratic invariants Runge-Kutta methods The aim of this note is to extend the analysis of B. 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. 2009-05-13T07:16:48Z http://zaguan.unizar.es/record/3275 info:eu-repo/semantics/publishedVersion Zaragoza Researchers Students Librarians
