Ratio Tauberian Theorems for Positive Functions and Sequences in Banach Lattices

Article

Abstract

We prove two ratio Tauberian theorems and deduce two generalized Tauberian theorems for functions and sequences with values in positive cones of Banach lattices. Two counter-examples are given to show that the hypotheses in the ratio Tauberian theorems are essential.
