We also define the inverse transform for this generalized transform based on the complex integration method. We prove some identities corresponding to the Laplace transform and inverse transform like the $q$-convolution theorem, the action of generalized derivative and generalized integration on the Laplace transform. We then derive a $q$-generalization of the inverse Laplace transform based on the Post-Widders method which bypasses the necessity for a complex contour integration. We demonstrate the usefulness of this in computing the Laplace and inverse Laplace transform of some elementary functions. Finally we use the Post-Widder's method based inverse Laplace transform to compute the density of states from the partition function for the case of a generalized ideal gas in three dimensions as also for a linear harmonic oscillator.", "revisions": [ { "version": "v1", "updated": "2022-05-07T04:16:10.000Z" } ], "analyses": { "keywords": [ "inverse laplace transform", "tsallis exponential", "inverse transform", "post-widders method", "linear harmonic oscillator" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable" } } }
