Inequalities for some basic hypergeometric functions

open access: yesПроблемы анализа, 2019
We establish conditions for the discrete versions of logarithmic concavity and convexity of the higher order regularized basic hypergeometric functions with respect to the simultaneous shift of all its parameters.

Multi-dimensional implementation of logarithmic dynamic skeleton constitutive model and its application in ABAQUS

open access: yesYantu gongcheng xuebao
The logarithmic dynamic skeleton constitutive model uses the logarithmic function as the skeleton curve and introduces the concepts of "modified dynamic skeleton curve" and "damping ratio degradation coefficient".

A foundation for analytical developments in the logarithmic region of turbulent channels [PDF]

open access: yes, 2014
An analytical framework for studying the logarithmic region of turbulent channels is formulated. We build on recent findings (Moarref et al., J. Fluid Mech., 734, 2013) that the velocity fluctuations in the logarithmic region can be decomposed into a ...

On logarithmic residue of monogenic functions in a three-dimensional commutative algebra with one-dimensional radical

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
We consider monogenic functions taking values in a three-dimensional commutative algebra A2 over the field of complex numbers with one- dimensional radical. We calculate the logarithmic residues of monogenic functions acting from a three-dimensional real

Vector valued logarithmic residues and the extraction of elementary factors [PDF]

open access: yes
An analysis is presented of the circumstances under which, by the extraction of elementary factors, an analytic Banach algebra valued function can be transformed into one taking invertible values only. Elementary factors are generalizations of the simple

On Certain Analytic Functions Associated with Nephroid Function

open access: yesAxioms
The normalized analytic function ΦN(z)=1+z−z33, which connects the open unit disk onto a bounded domain within the right half of a nephroid-shaped region, is associated with the bounded turning of functions denoted by Rn.

Nesting Quadratic Logarithmic Demand Systems [PDF]

open access: yes
We propose a new generalised rank-3 demand system which nests all known (and new) rank-3 and rank-2 demand systems derived from the Quadratic Logarithmic (QL) cost function.

A Critical Analysis of Dimensions and Curve Fitting Practice in Economics [PDF]

open access: yes
When dealing with sustainability we are concerned with the biophysical as well as the monetary aspects of economic and ecological interactions. This multidimensional approach requires that special attention is given to dimensional issues in relation to ...
