We classify them in several categories depending on the asymptotic principles from which they are obtained: classical methods based on Watson's lemma, summability methods, distributional methods, Mellin transform techniques, integration by parts, and so on.
of the product Y, we take double Mellin transform of eq.
Following Hadamard's precept, these problems are tackled by complex analysis methods such as generating functions, Mellin transform, Fourier series, saddle point method, analytic poissonization and depoissonization, and singularity analysis.
This will be achieved essentially by using the Mellin transform technique.
He also develops Mellin transform techniques used to evaluate said integrals analytically and express the results either as infinite series or as sums of generalized hypergeometric functions.
However, we could not take the multiple Mellin transform to define multiple p-adic L-function which interpolates multiple Bernoulli numbers.

Using the well-known properties of the Mellin transform (see (FGD95) and (Szp01)), it follows that
The proof of Proposition 2 consists of three steps: (i) the Poisson expectation is first expressed in integral form (Equation (9)); (ii) the integrand is next analysed by means of the Mellin transform (Lemma 1); (iii) the outcome of the local Mellin analysis is finally used to estimate the Poisson expectation.

It is also shown from an analysis of the moving poles of the Mellin transform of the poissonized moment generating function that the imbalance factor (under appropriate centering and scaling) follows a Gaussian limit law.
