Once more on the Telyakovskii'S class S

Research output: Contribution to journalArticle


We show once more the vitality and usability of the class S of numerical sequences. It is almost hopeless to give a real extension of the class S keeping the conditions ΣAn < ∞ and |δan| ≤ An. Among others we give two further virtual extensions of S which are truly equivalent to S.
