The uniform estimates are obtained for the monotone approximation of functions from generalized Babenko classes. 1993-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/153150 Сходимость рядов из вероятностей больших уклонений сумм независимых одинаково распределенных случайных величин Клесов, О.И. The series ∑n≥1τnP(|Sn|≥ εnα) is studied, where Sn are the sums of independent equally distributed random variables, τn is a sequence of nonnegative numbers, α>0, and ε>0 is an arbitrary positive number. For a broad class of sequences τn, the necessary and sufficient conditions are established for the convergence of this series for any ε>0. 1993-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/153141 Матрица рассеяния для волнового уравнения с финитным радиальным потенциалом в двумерном пространстве Мильман, А.Л. The expressions for partial scattering matrices Sl(λ) are obtained for any natural l by vising V. M. Adamyan's result which establishes the universal relationship between the scattering matrix for a wave equation with finite potential in an even-dimensional space and a characteristic operator function of a special contraction operator which describes the energy dissipation from the domain of the space which contains a dissipator. It is shown that the problem can be reduced to the case of l=0 for all even l and to the case of l=1 for all odd l. 1993-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/153136 Об асимптотической оценке наилучших приближений дифференцируемых функций алгебраическими многочленами в пространстве L₁ Моторная, О.В.
