A theorem on the expansion of the derivative f(r1; r2; :::; rn); where f 2 Lp; and the derivatives of singular integrals into the series of band - limited functions ( entire functions of exponential type ) , which converges in Lp for 1 p q < 1; is proved . The norms of their items are estimated by best approximations by \ an \
