On Hyers-Ulam stability for a class of functional equations

open access: yesAequationes Mathematicae, 1997
In this paper we prove some stability theorems for functional equations of the formg[F(x, y)]=H[g(x), g(y), x, y]. As special cases we obtain well known results for Cauchy and Jensen equations and for functional equations in a single variable.

Explicit Runge-Kutta-Chebyshev methods of second order with monotonic stability polynomial [PDF]

open access: yesarXiv
A new Chebyshev-type family of stabilized explicit methods for solving mildly stiff ODEs is presented. Besides conventional conditions of order and stability we impose an additional restriction on the methods: their stability function must be monotonically increasing and positive along the largest possible interval of negative real axis.
