The Average Case Analysis of Algorithms: Mellin Transform Asymptotics
, 1996 . This report is part of a series whose aim is to present in a synthetic way the major methods of "analytic combinatorics" needed in the average--case analysis of algorithms. It reviews the use of Mellin-Perron formulae and of Mellin transforms

Second Microlocalization and the Mellin Transformation
Publications of the Research Institute for Mathematical Sciences, 1990 The authors define the second wave front set WF in a way analogous to the definition of the first wave front set, using the Mellin transformation, instead of the Fourier transform. In particular they give another proof of Bony's theorem on propagation of 2-microlocal singularities: Theorem (Bony) - Let \({\overset \circ \xi}=(0,{\overset \circ \xi}')\)

IET Image Processing, Volume 20, Issue 1, January/December 2026.This paper presents a robust reversible watermarking algorithm based on Chebyshev moments, employing a two‐stage embedding mechanism. The proposed method leverages image block partitioning to embed the copyright watermark and the reversible watermark into non‐overlapping regions located inside and outside the inscribed circle of the image, respectively.

Null infinity and unitary representation of the Poincare group
Journal of High Energy Physics, 2019 Following Pasterski-Shao-Strominger we construct a new basis of states in the single-particle Hilbert space of massless particles as a linear combination of standard Wigner states.

Local affine image matching and synthesis based on structural patterns [PDF]
, 2010 A general purpose block-to-block affine transformation estimator is described. The estimator is based on Fourier slice analysis and Fourier spectral alignment.

Nonterminating transformations and summations associated with some q-Mellin--Barnes integrals
, 2022 In many cases one may encounter an integral which is of $q$-Mellin--Barnes type. These integrals are easily evaluated using theorems which have a long history dating back to Slater, Askey, Gasper, Rahman and others. We derive some interesting $q$-Mellin--

Error estimates and extrapolation for the numerical solution of Mellin convolution equations [PDF]
, 1994 In this paper we consider a quadrature method for the numerical solution of a second kind integral equation over the interval, where the integral operator is a compact perturbation of a Mellin convolution operator.

Mellin analysis of weighted Sobolev spaces with nonhomogeneous norms on cones
, 2009 On domains with conical points, weighted Sobolev spaces with powers of the distance to the conical points as weights form a classical framework for describing the regularity of solutions of elliptic boundary value problems, cf.\ papers by Kondrat'ev and ...

The finite Mellin transform, Mellin-fourier series, and the Mellin-poisson summation formula
, 1997 The aim of this paper is to present the counterpart of the theory of Fourier series in the Mellin setting in a systematic form, independently of the Fourier theory, under natural and minimal assumption upon the functions in question. Such Mellin (Fourier)
