GKZ-system of the 2-loop self energy with 4 propagators

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Applying the system of linear partial differential equations derived from the Mellin–Barnes representation and the Miller transformation, we present the GKZ-system of the Feynman integral of the 2-loop self energy diagram with 4 propagators.

A transformation formula with primitive character

open access: yesLietuvos Matematikos Rinkinys, 2013
We prove a transformation formula for the exponential sum involving the divisor function, and primitive character modulo q. This formula can be applied to obtain meromorphic continuation for the Mellin transform of the square of Dirichlet L-function with

A transformation formula related to Dirichlet L-functions with principal character

open access: yesLietuvos Matematikos Rinkinys, 2012
We prove a transformation formula for the function for the exponential sum involving the divisor function. This formula can be applied to obtain meromorphic continuation for the Mellin transform of the square of Dirichlet L-function with principal ...

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.

The n-dimensional distributional Mellin transformation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1983
The n-dimensional distributional Mellin transformation is developed using the testing function space Mc,d and its dual M′c,d The standard theorems on analyticity, uniqueness and continuity are proved.

Mellin Transforms of Whittaker Functions [PDF]

open access: yesCanadian Mathematical Bulletin, 2002
AbstractIn this note we show that for an arbitrary reductive Lie group and any admissible irreducible Banach representation the Mellin transforms of Whittaker functions extend to meromorphic functions. We locate the possible poles and show that they always lie along translates of walls of Weyl chambers.

Waveform considerations in space-variant optical processors [PDF]

open access: yes, 1978
The use of coded waveforms in space-variant optical signal processors using coordinate transformations is considered. It is shown that nonlinear transmitted coded signals must be used with such a processor and that this results in novel waveform design ...

GKZ hypergeometric systems of the three-loop vacuum Feynman integrals

open access: yesJournal of High Energy Physics, 2023
We present the Gel’fand-Kapranov-Zelevinsky (GKZ) hypergeometric systems of the Feynman integrals of the three-loop vacuum diagrams with arbitrary masses, basing on Mellin-Barnes representations and Miller’s transformation. The codimension of derived GKZ

Dual parametrization of generalized parton distributions in two equivalent representations [PDF]

open access: yes, 2014
The dual parametrization and the Mellin-Barnes integral approach represent two frameworks for handling the double partial wave expansion of generalized parton distributions (GPDs) in the conformal partial waves and in the $t$-channel ${\rm SO}(3 ...
