Regular Summability

In 1945 Brudno presented the following important theorem: If $A$ and $B$ are regular summability matrix methods such that every bounded sequence summed by $A$ is also summed by $B$, then it is summed by $B$ to the same value. R. G. Cooke suggested that a simpler proof would be desirable. Petersen presented such a proof. The goal of the paper is to present an accessible multidimensional analog of Brudno theorem for double sequences using four dimensional matrix transformations.

Multidimensional Analog

In 1946 P. Erdos and P. C Rosenbloom presented the following theorem that arose out of discussions they had with R. P. Agnew. Let {xn} be a bounded divergent sequence. Suppose that {xn} is summable by every regular Toeplitz method which sums {xn}. Then {yn} is of the form {cxn + an} where {an} is convergent. The goals of the paper includes the presentation of a multidimensional analog of Erdos and Rosenbloom results in [1].

В статье рассматривается одно из дополнений к фундаментальным результатам геометрической теории многомерного комплексного анализа по проблемам классов голоморфных функций. По радиусам параметризации границ областей Рейнхарта строятся эффективные достаточные условия обобщенно-звездных функций в виде многомерного аналога гипотезы Бибербаха.
