About Characters and the Dirichlet Kernel on Vilenkin Groups

Sarajevo Journal of Mathematics
In this paper we study properties of characters and the Dirichlet kernel on Vilenkin groups which are of key importance for analyzing convergence, integrability and summability of Fourier-Vilenkin series.   2000 Mathematics Subject Classification.

On the a. e. convergence of Fourier series on unbounded Vilenkin groups

1999
Summary: It is well known that the \(2^n\)th partial sums of the Walsh-Fourier series of an integrable function converges a.e. to the function. This result has been proved by \textit{W. M. Stout} [``Almost sure convergence'' (1974; Zbl 0321.60022)] using techniques known in the martingale theory.
