Approximation of analytic functions by Hermite functions. (English) Zbl 1186.41016
The author solves the inhomogeneous Hermite equation with a power series on the right. This is used to establish the error bound $$O(x^2)$$, $$x \to 0$$, for the approximation of an analytic function by a solution of the homogeneous Hermite equation.
