D-splitting methods: 2N -storage embedded explicit pseudo-geometric Runge-Kutta methods using splitting methods

Sergio Blanes, Alejandro Escorihuela-Tomà s

Low-storage explicit Runge-Kutta schemes are particularly popular for the numerical integration of time-dependent partial differential equations based on the method-of-lines due to…

On a class of modified Cayley--Magnus methods

Sergio Blanes, Fernando Casas, Arieh Iserles

We introduce a new class of numerical integrators for the time integration of non-autonomous linear ordinary differential equations whose coefficient matrix is sparse and evolves w…

Generalized extrapolation methods based on compositions of a basic 2nd-order scheme

Sergio Blanes, Fernando Casas, Luke Shaw

We propose new linear combinations of compositions of a basic second-order scheme with appropriately chosen coefficients to construct higher order numerical integrators for differe…

Families of efficient low order processed composition methods

Sergio Blanes, Fernando Casas, Alejandro Escorihuela-Tomà s

New families of composition methods with processing of order 4 and 6 are presented and analyzed. They are specifically designed to be used for the numerical integration of differen…
