Nested Second Derivative Two-Step Runge–Kutta Methods
Two-step Runge–Kutta (TSRK) methods are Runge–Kutta methods that depend on stage values at two consecutive steps. Second derivative Two-step Runge–Kutta (SD-TSRK) methods are extension of TSRK methods in which second derivatives as well as first derivatives are computed. General linear methods (GLMs...

Zusammenfassung: | Two-step Runge–Kutta (TSRK) methods are Runge–Kutta methods that depend on stage values at two consecutive steps. Second derivative Two-step Runge–Kutta (SD-TSRK) methods are extension of TSRK methods in which second derivatives as well as first derivatives are computed. General linear methods (GLMs) were introduced as a generalization of Runge–Kutta methods and linear multistep methods, and have also been extended to second derivative general linear methods (SD-GLMs). This paper presents SD-TSRK methods that are nested in their stages and mono-implicit in their output as SD-GLMs; these methods are referred to as nested second derivative two-step Runge–Kutta methods.
