The Mellin Transform of Logarithmic and Rational Quotient Function in terms of the Lerch Function

open access: yesJournal of Mathematics, 2021
Upon reading the famous book on integral transforms volume II by Erdeyli et al., we encounter a formula which we use to derive a Mellin transform given by ∫0∞xm−1logkax/β2+x2γ+xdx, where the parameters a,k,β, and γ are general complex numbers.

Renormalization and Mellin Transforms [PDF]

open access: yes, 2013
We study renormalization in a kinetic scheme using the Hopf algebraic framework, first summarizing and recovering known results in this setting. Then we give a direct combinatorial description of renormalized amplitudes in terms of Mellin transform coefficients, featuring the universal property of rooted trees H_R.

Integrable field theories and their CCFT duals

open access: yesJournal of High Energy Physics, 2023
We compute the Mellin transforms of various two-dimensional integrable S-matrices, providing the first explicit, non-perturbative realizations of celestial CFT.

Mellin amplitudes for 1d CFT

open access: yesJournal of High Energy Physics, 2021
We define a Mellin amplitude for CFT1 four-point functions. Its analytical properties are inferred from physical requirements on the correlator. We discuss the analytic continuation that is necessary for a fully nonperturbative definition of the Mellin ...

On Approximation by an Absolutely Convergent Integral Related to the Mellin Transform

open access: yesAxioms, 2023
In this paper, we consider the modified Mellin transform of the product of the square of the Riemann zeta function and the exponentially decreasing function, and we discuss its probabilistic and approximation properties.

Computing the Inverse Mellin Transform of Holonomic Sequences using Kovacic's Algorithm [PDF]

open access: yesarXiv.org, 2018
We describe how the extension of a solver for linear differential equations by Kovacic's algorithm helps to improve a method to compute the inverse Mellin transform of holonomic sequences.

Mellin Transform-Based Approach for Parameter Estimation of K Distribution Plus Noise

open access: yesIEEE Access, 2019
Mellin transform is a fast and robust method for parameter estimation. In this paper, the parameter estimator of K plus noise (KpN) model based on the Mellin transform is proposed.

The Fourier, Hilbert and Mellin transforms on a half-line [PDF]

open access: yesBl{\aa}sten, E. L. K., P\"aiv\"arinta, L., Sadique, S. (2023). The Fourier, Hilbert, and Mellin transforms on a half-line. SIAM Journal on Mathematical Analysis, 55(6), 7529-7548, 2023
We are interested in the singular behaviour at the origin of solutions to the equation $\mathscr{H} \rho = e$ on a half-axis, where $\mathscr H$ is the one-sided Hilbert transform, $\rho$ an unknown solution and $e$ a known function. This is a simpler model problem on the path to understanding wave field singularities caused by curve-shaped scatterers ...

Theory of Barnes Beta Distributions [PDF]

open access: yes, 2013
A new family of probability distributions $\beta_{M, N},$ $M=0\cdots N,$ $N\in\mathbb{N}$ on the unit interval $(0, 1]$ is defined by the Mellin transform.

Pricing of Barrier Options on Underlying Assets with Jump-Diffusion Dynamics: A Mellin Transform Approach

open access: yes, 2020
A barrier option is an exotic path-dependent option contract where the right to buy or sell is activated or extinguished when the underlying asset reaches a certain barrier price during the lifetime of the contract.
