    • Global Time-Renormalization of the Gravitational N-body Problem 

      Antoñana, M.; Chartier, P.; Makazaga, J.; Murua, A. (2021-01-01)
      This work considers the gravitational N-body problem and introduces global time-renormalization functions that allow the efficient numerical integration with fixed time-steps. First, a lower bound of the radius of convergence ...
