Abstract

We have obtained the estimate in the terms of partial and mixed moduli of continuity of deviation of Cesáro (C, ) means of the sequence of rectangular partial sums of n-multiple (n > 1) conjugate trigonometric series from n-multiple truncated conjugate function. This estimate implies the result on the -convergence (⋋ ≥ 1) of (C, ) means , provided that the essential conditions are imposed on the partial moduli of continuity. Finally, it is shown, that the -convergence cannot be replaced by ordinary convergence.
