An Exact Analytical Solution for Gaseous Flow and Heat Transfer in Microtubes with Constant Wall Temperature [PDF]

open access: yesJournal of Heat and Mass Transfer Research, 2021
It is known that slip flow and temperature jump phenomena play a significant role in micro-scale investigations. In this paper, exact analytical solutions for the flow and the convective heat transfer of gaseous flow passing through microtubes are ...

Exponential beams of electromagnetic radiation [PDF]

open access: yes, 2006
We show that in addition to well known Bessel, Hermite-Gauss, and Laguerre-Gauss beams of electromagnetic radiation, one may also construct exponential beams.

Dynamics of the Dirac Particle in an Anisotropic Rainbow Universe

open access: yesCumhuriyet Science Journal, 2022
An alternative way of understanding physical effects in curved space time is to solve the associated particle equation such as the Dirac equation. It is a first-order relativistic wave equation and defines spin-1/2 massive particles like electrons and ...

End of the world brane in double scaled SYK

open access: yesJournal of High Energy Physics, 2023
We study the end of the world (EOW) brane in double scaled SYK (DSSYK) model. We find that the boundary state of EOW brane is a coherent state of the q-deformed oscillators and the associated orthogonal polynomial is the continuous big q-Hermite ...

Parabolic Whittaker Functions and Topological Field Theories I

open access: yes, 2010
First, we define a generalization of the standard quantum Toda chain inspired by a construction of quantum cohomology of partial flags spaces GL(\ell+1)/P, P a parabolic subgroup. Common eigenfunctions of the parabolic quantum Toda chains are generalized

Whittaker's Constant for Lacunary Entire Functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1963
be an entire function of exponential type r < oo. We are concerned here with two problems which are closely related to the determination of Whittaker's constant, that is to say, with theorems to the effect that if f(z) and each of its derivatives have some zeros in the unit circle then r cannot be too small. DEFINITION 1. The constant Wp is the largest

Simple Method of Light Field Calculation for Shaping of 3D Light Curves

open access: yesPhotonics, 2023
We propose a method for generating three-dimensional light fields with given intensity and phase distributions using purely phase transmission functions.

On the Whittaker Function Extended by the Fox–Wright Function and Its Properties

open access: yesMathematics
This paper aims to obtain the Ψηξ-extended Whittaker function and its integral representations. This function is defined by using the Ψηξ-confluent hypergeometric function, which was recently extended in terms of the Fox–Wright function.

Generalized Fractional Integral Operators Involving Mittag-Leffler Function

open access: yesAbstract and Applied Analysis, 2018
The aim of this paper is to study various properties of Mittag-Leffler (M-L) function. Here we establish two theorems which give the image of this M-L function under the generalized fractional integral operators involving Fox’s H-function as kernel ...

Effect of rigid boundary on Rayleigh wave in an incompressible heterogeneous medium over an incompressible half-space

open access: yesAIMS Mathematics, 2020
In the present problem, an attempt has been made to study the propagation of Rayleigh waves in an incompressible medium with polynomial variation (m) of rigidity over an incompressible half-space under rigid layer. Instead of using the Whittaker function,
