      Casas, Fernando; Sanz-Serna, JM; Shaw, Luke Society for Industrial and Applied Mathematics (2023)
      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 ...
