Kroó, A.; Szabados, J.; Varga, R. S. Weighted polynomial approximation of some entire functions on the real line. (English) Zbl 0885.41008 Ann. Numer. Math. 4, No. 1-4, 405-413 (1997). 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.
