On the divergence of greedy algorithms with respect to Walsh subsystems in
Sergo A. Episkoposian
In this paper we prove that there exists a function which belongs to such that a greedy algorithm with regard to the Walsh subsystem does not converge to i…
Existence of double Walsh series universal in weighted spaces
Sergo A. Episkoposian
In this paper we consider a question on existence of double Walsh series universal in weighted spaces. We construct a weighted function and a series by doub…
Universal series by trigonometric system in weighted spaces
Sergo A. Episkoposian
In this paper we consider the question of existence of trigonometric series universal in weighted spaces with respect to rearrangements and in usual sense.
- convergence of greedy algorithm by generalized Walsh system
Sergo A. Episkoposian
In this paper we consider the generalized Walsh system and a problem of greedy algorithm of functions after changing the values on small set.
Universality properties of double series by generalized Walsh system
S. A. Episkoposian
In this paper we consider a question on existence of double series by generalized Walsh system, which are universal in weighted spaces. In particular, we construct a…
