2N-storage Runge-Kutta methods: c-reflection symmetry and factorization of the Butcher tableau
Alexei Bazavov
Low-storage Runge-Kutta schemes of Williamson's type, so-called 2N-storage schemes, are further examined as a follow-up to the recent work. It is found that the augmented Butcher t…

2N-storage Runge-Kutta methods: Order conditions, general properties and some analytic solutions
Alexei Bazavov
Low-storage Runge-Kutta schemes of Williamson's type, so-called 2N-storage schemes, are examined. Explicit 2N-storage constraints are derived for the first time and used to establi…
