Since the publication of an article by G. DOETSCH in 1927 it has been known that the Laplace transform procedure is a reliable sub- stitute for HEAVISIDE'S operational calculus*. However, the Laplace transform procedure is unsatisfactory from several viewpoints (some of these will be mentioned in this preface); the most obvious defect: the procedure cannot be applied to functions of rapid growth (such as the 2 function t ~ exp (t )).
