A theorem of Galambos-Bojanić-Seneta type (Q1030646)

Summary: In the theorems of Galambos-Bojanić-Seneta's type, the asymptotic behavior of the functions \(c_{[x]},\, x\geq 1\), for \(x\rightarrow +\infty\), is investigated by the asymptotic behavior of the given sequence of positive numbers \((c_{n})\), as \(n\rightarrow +\infty \) and vice versa. The main result of this paper is one theorem of such a type for sequences of positive numbers \((c_{n})\) which satisfy an asymptotic condition of the Karamata type \(\underline{\lim}_{n \to \infty} c_{[\lambda n]}/c_n > 1\), for \(\lambda >1\).
