A Framework for Algorithm Stability [PDF]

open access: yes, 2017
We say that an algorithm is stable if small changes in the input result in small changes in the output. This kind of algorithm stability is particularly relevant when analyzing and visualizing time-varying data.

Formal series and numerical integrators: some history and some new techniques [PDF]

open access: yes, 2015
This paper provides a brief history of B-series and the associated Butcher group and presents the new theory of word series and extended word series. B-series (Hairer and Wanner 1976) are formal series of functions parameterized by rooted trees.

Finite element or Galerkin type semidiscrete schemes [PDF]

open access: yes
A finite element of Galerkin type semidiscrete method is proposed for numerical solution of a linear hyperbolic partial differential equation. The question of stability is reduced to the stability of a system of ordinary differential equations for which ...
