The problem of finding estimates for the \(L_ p\)-norm of the approximation error f-Lf, where f is a real valued \(L_ p\)-integrable function and L is a positive linear operator, has been extensively discussed in the literature. See, for example, \textit{H. Berens} and \textit{R. A. DeVore} [Trans. Am. Math. Soc. 245, 349-361 (1978; Zbl 0397.41010)]. The author obtains \(L_ p\)-error estimates for positive operators using the second-order \(\tau\)-modulus.
