• TITLE: Representation of Functions in L1μ Weighted Spaces by Series with Monotone Coefficients in the Walsh Genrealized System

  AUTHORS: Martin Grigoryan, Artavazd Minasyan

  KEYWORDS: Orthonormal System; Convergence; Functional Series

  JOURNAL NAME: Applied Mathematics, Vol.4 No.11A, October 31, 2013

  ABSTRACT: Let is the Walsh generalized system. In the paper constructed a weighted space , and series in the Walsh generalized system with monotonically decreasing coefficient such that for each function in the space one can find a subseries that converges to in the weighted and almost everywhere on [0,1].
