GCS - Geometry, compatibility and structure preservation in computational differential equations

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.
