Ulam stability of a linear difference equation in locally convex spaces

Abstract

We obtain a characterization of Ulam stability for the linear difference equation with constant coefficients $$x_{n+p}=a_₁x_{n+p-1}+…+a_{p}x_{n}$$ in locally convex spaces. Moreover, for the first order linear difference equation we determine the best Ulam constant.
