We obtain a characterization of Ulam stability for the linear difference equation with constant coefficients $$x_{n+p}=a_1x_{n+p-1}+\cdots +a_px_n$$ x n + p = a 1 x 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.

我们获得了具有常系数的线性差分方程的 Ulam 稳定性表征 $$x_{n+p}=a_1x_{n+p-1}+\cdots +a_px_n$$xn + p = a 1 xn + p - 1 + ⋯ + apxn 在局部凸空间中。此外,对于一阶线性差分方程,我们确定最佳 Ulam 常数。
