✦ Synopsis

Abstract

A unified class of linear positive operators has been defined. Using these operators some approximation estimates have been obtained for unbounded functions. For particular linear positive operators these results sharpen and improve the earlier estimates due to Fuhua Cheng (J. Approx. Theory, 1984) and Xiehua Sun (J. Approx. Theory, 1988).

Given a function analytic in an unbounded domain of \(\mathbb{C}^{n}\) with certain estimates of growth, we construct an entire function approximating it with a certain rate in some inner domain and give estimates of growth of the approximating function. This extends well-known results of M. V. Keld
