Hyers-Ulam stability for differential systems with constant coefficient matrix
Douglas R. Anderson, Masakazu Onitsuka
We explore the Hyers-Ulam stability of perturbations for a homogeneous linear differential system with constant coefficient matrix. New necessary and sufficient conditi…
Hyers--Ulam stability for quantum equations
Douglas R. Anderson, Masakazu Onitsuka
We introduce and study the Hyers--Ulam stability (HUS) of a Cayley quantum (-difference) equation of first order, where the constant coefficient is allowed to range over the com…
Best constant for Ulam stability of first-order h-difference equations with periodic coefficient
Douglas R. Anderson, Masakazu Onitsuka, John Michael Rassias
We establish the best (minimum) constant for Ulam stability of first-order linear -difference equations with a periodic coefficient. First, we show Ulam stability and find the U…
Box-counting dimension of solution curves for a class of two-dimensional nonautonomous linear differential systems
Masakazu Onitsuka, Satoshi Tanaka
A class of two-dimensional linear differential systems is considered. The box-counting dimension of the graphs of solution curves is calculated. Criteria to obtain the box-counting…
