چکیده

For Runge–Kutta methods and linear multistep methods, much attention has been paid, in the literature, to special nonlinear stability properties indicated by the terms total-variationdiminishing (TVD), strong-stability-preserving (SSP), and monotonicity. Stepsize conditions, guaranteeing these properties, were studied, e.g., by Shu and Osher [J. Comput. Phys., 77 (1988), pp. 439–471], Gottlieb, Shu, and Tadmor [SIAM Rev., 43 (2001), pp. 89–112], Hundsdorfer and Ruuth [Monotonicity for Time Discretizations, Dundee Conference Report NA/217 2003, University of Dundee, Dundee, UK, 2003, pp. 85–94], Higueras [J. Sci. Comput., 21 (2004), pp. 193–223] and [SIAM J. Numer. Anal., 43 (2005), pp. 924–948], Spiteri and Ruuth [SIAM J. Numer. Anal., 40 (2002), pp. 469–491], Gottlieb [J. Sci. Comput., 25 (2005), pp. 105–128], and Ferracina and Spijker [SIAM J. Numer. Anal., 42 (2004), pp. 1073–1093] and [Math. Comp., 74 (2005), pp. 201–219]. In the present paper, we obtain a special stepsize condition guaranteeing the above properties, for a generic numerical process. This condition is best possible in a well defined and natural sense. It is applicable to the important class of general linear methods, and it can also be used to answer some open questions, for methods of which the above stability properties were studied earlier.

Stability and boundedness in the numerical solution of initial value problems

This paper concerns the theoretical analysis of step-by-step methods for solving initial value problems in ordinary and partial differential equations. The main theorem of the paper answers a natural question arising in the linear stability analysis of such methods. It guarantees a (strong) version of numerical stability – under a stepsize restriction related to the stability region of the nume...

An adaptive stepsize algorithm for the numerical solving of initial-value problems

The present paper focuses on the efficient numerical solving of initialvalue problems (IVPs) using digital computers and one-step numerical methods. We start from considering that the integration stepsize is the crucial factor in determining the number of calculations required and the amount of work involved to obtain the approximate values of the exact solution of a certain problem for a given...
