Kasana, H. S. On simultaneous approximation by linear combination of Szász-Mirakian operators. (English) Zbl 0776.41007 Rev. Roum. Math. Pures Appl. 37, No. 6, 491-498 (1992). The author gives a theorem on simultaneous approximation by linear combination of Szasz-Mirakian operators of elements of a certain class of unbounded functions. The result given here extends and improves upon some previous results of X. Sun [J. Approximation Theory 55, No. 3, 279- 288 (1988; Zbl 0697.41009)], J. Grof [Magyar Tud. Akad. Mat. Fiz. Oszt. Köszl. 20, 35-44 (1971; Zbl 0219.41010)] and B. Wood [J. Approximation Theory 45, 375-382 (1985; Zbl 0617.41037)].
