Extensions of democracy-like properties for sequences with gaps

Abstract

In \cite{O2015}, T. Oikhberg introduced and studied variants of the greedy and weak greedy algorithms for sequences with gaps. In this paper, we extend some of the notions that appear naturally in connection with these algorithms to the context of sequences with gaps. In particular, we will consider sequences of natural numbers for which the inequality nk+1\Cnkn_{k+1}\le \C n_{k} or nk+1\C+nkn_{k+1}\le \C+n_k holds for a positive constant \C\C and all kk, and find conditions under which the extended notions are equivalent their regular counterparts.
