Resumen
For systems of the form ̇q = M−1 p, ̇p = −Aq + f(q), common in many applications, we analyze splitting
integrators based on the (linear/nonlinear) split systems ̇q = M−1 p, ̇p = −Aq and ̇q = 0, ̇p = f(q). We ... [+]
For systems of the form ̇q = M−1 p, ̇p = −Aq + f(q), common in many applications, we analyze splitting
integrators based on the (linear/nonlinear) split systems ̇q = M−1 p, ̇p = −Aq and ̇q = 0, ̇p = f(q). We show that the
well-known Strang splitting is optimally stable in the sense that, when applied to a relevant model problem, it has a larger
stability region than alternative integrators. This generalizes a well-known property of the common St ̈ormer/Verlet/leapfrog
algorithm, which of course arises from Strang splitting based on the (kinetic/potential) split systems ̇q = M−1 p, ̇p = 0 and
q ̇ = 0, ̇p = −Aq + f(q). [-]
