We provide a new version of the Wiener-Ikehara theorem where one deduces bounds 0< \liminfx→∞ \fracS(x)ex≤ \limsupx→∞ \fracS(x)ex <∞ for (in particular) a non-decreasing function S from a mild hypothesis on the boundary behavior of its Laplace transform on a vertical segment containing s=1. As an application, we establish new criteria for the validity of Chebyshev bounds for Beurling generalized prime number systems under weaker conditions than were known so far.
