On the Rate of Convergence by Generalized Baskakov Operators

We firstly construct generalized Baskakov operators Vn,α,q(f;x) and their truncated sum Bn,α,q(f;γn,x). Secondly, we study the pointwise convergence and the uniform convergence of the operators Vn,α,q(f;x), respectively, and estimate that the rate of convergence by the operators Vn,α,q(f;x) is 1/nq/...
