Weighted polynomial approximation of some entire functions on the real line. (English) Zbl 0885.41008

The authors study here weighted uniform approximation by polynomials of a continuous function on the whole real line. As a corollary of their main theorem they sharpen the Akhiezer-Koosis theorem.
