Abstract

We define and study an equivalence relation in the class ${\sf Tr(SV_s)}$ of translationally slowly varying positive real sequences and its relations with selection principles and game theory. We also prove a game-theoretic result for translationally rapidly varying sequences.

Keywords

Rapid equivalence, Class $R_{s;\infty}$, Selection principles
