Equivalent sequences. (Suites équivalentes.) (French) Zbl 0789.11005
Four relations are defined between increasing infinite sequences of integers; for instance, the first holds if $$A(x)-B(x)=o(x)$$, the second if $$A(x)/B(x) \to 1$$. Connections between these relations and their impacts on several concepts of density are explored.
