Abstract: | Suppose that (X, p) is a sermonized space, is a linearly independent system of elements in X, is a sequence of linear bounded functionals such that c

(x

,
are the Riesz sums. We prove general assertions concerning estimates from above for the values of semiadditive functionals
by deviations of the Riesz sums p(x − R
