“…In such cases we must use some methods for its approximative computation for a given t > 0. Different methods for numerical inversion of the Laplace transform were described in several papers [11], [35], [16], [1], [2], [36], [26], [38], [14], [10], [37], which include Fourier series expansions, Laguerre and Puiseux expansions, a combination of Gaver functionals, different deformations of the Bromwich contour, as well as a method based on Müntz systems (see [24], [25]). By determining the values f 1 (t ν ) on a particular discrete set T = {t ν } ν , we are able to obtain an approximation formula, usually interpolation (cf.…”
