| Abstract: | In this talk I will review composition methods for the time integration of differential equations,
paying special attention to two recent contributions in this area. The first one is the construction of a new local error estimator so that the additional computational effort required is almost insignificant. The second one is related to a new family of high-order methods obtained from a basic symmetric (symplectic) scheme in such a way that they are time-symmetric (symplectic) only up to a certain order. |
