Abstract:
      The present paper investigates the convergence of Hermite interpolation operators on the real line. The main result is: Given $0<\delta_{0}<1/2$, $0<\epsilon_{0}<1$. Let $f\in C_{(- \infty,\infty)}$ satisfy $|y_{k}| = O(e^{(1/2-\delta_{0})x_{k}^{2}})$ and $|f(x)| = O(e^{(1-\epsilon_{0})x^{2}})$. Then for any given point $x\in \R$, we have $\lim_{n\to\infty}H_{n}(f,x)=f(x)$.
