✦ Synopsis


In this paper we have converted the Laplace transform to an integral equation of the first kind of convolution type, which is an ill-posed problem and used the spline regularization method to solve it. Inversion of perturbed Laplace transforms also plays an important role in system theory. The method is applied to several test examples taken from [1-3, 8, 11, 22]. It gives a good approximation to the true solution and compares well with the methods discussed in [1-3, 8, 11, 22]. The results are shown in Table 1 and respective diagrams.

Most methods for the numerical calculation of inverse Laplace transformations f(t) = L -1 [F(s)] have serious limitations concerning the class of functions F(s) that can be inverted or the achievable accuracy. The procedures described in the paper can be used to invert rational as well as irrational

A new technique of inverting Moments and Laplace Transforms is presented, using a finite series of generalized Laguerre polynomials in the variable t = ln(1/x). The method is tested with two different functions, with particular emphasis on the estimation of errors involved. The applications of momen
