On the (C, –1 < α < 0)-Summability of Series with Respect to Block-Orthonormal Systems
Abstract Statements connected with the (C, α) (–1 < α < 0)-summability almost everywhere of series with respect to block-orthonormal systems are given. In particular, it is stated that if , then the condition guarantees the (C, α)-summability almost everywhere of the series with respect to an {ϕ n } – (Nk , Nk +1]-orthonormal system.
