Nonlinear approximation of functions from the class $L^r$ with respect to the Vilenkin system
M. G. Grigoryan, S. A. Sargsyan Chair of Higher Mathematics, Erevan State University, Erevan, Republic of Armeniya
Abstract:
In this paper we prove that for any function $f$ from the class $L^r$ on $[0,1)$ one can find a function $g$ from the same class (which differs from $f$ on a set of arbitrarily small measure) whose greedy algorithm with respect to the Vilenkin system converges to $f$.
Keywords:
Vilenkin system, greedy algorithm, Fourier coefficients.
