Open publisher page 1 citations

Abstract

We develop necessary and sufficient conditions for a function to be represented as a Laplace or Laplace–Stieltjes transform by considering the behaviour of the function on a single vertical line. Various kernels, based on ideal inversion kernels for the Fourier transform, are considered and three new inversion formulae for the Laplace transform are developed.
