Abstract

The convergence of families of linear polynomial operators in the scale of the $L_p$-spaces with $0<p<+\infty$ is studied. The convergence conditions are formulated in terms of the Fourier transform of the generator of the kernel. The results are applied to methods generated by classical kernels.
