Abstract
We show that it is possible to define extensions of the Laplace transform
that use a general Dirichlet series as a kernel. These transforms, denoted by DLTs, further generalize
those, considered in previous papers, in which the kernels were related to Laguerre-type exponentials or
Bell polynomials. Computational techniques, exploiting expansions in Laguerre polynomials, and using Tricomi's
method, have been considered. Since it turns out that the transforms considered are obtained as linear
combinations of ordinary Laplace transforms, it is also possible to define an approximation of the relevant
inverse transforms. Numerical experiments, performed with the algebra program Mathematica,
show that the introduced technique is fast and efficient.
