Differential transcendence criteria for second-order linear difference equations and elliptic hypergeometric functions [PDF]

open access: yes, 2019
We develop general criteria that ensure that any non-zero solution of a given second-order difference equation is differentially transcendental, which apply uniformly in particular cases of interest, such as shift difference equations, q-dilation ...

Selective solutions to transcendental equations

open access: yesComputers & Mathematics with Applications, 1991
The authors present a combination of global iterative methods, based on the Fatou-Julia theory, and local methods to find selected roots of elementary transcendental equations, \(z=F(z,c)\), \(z\) and \(c\) complex, that occur in different applications.

Harmonic elimination of a fifteen‐level inverter with reduced number of switches using genetic algorithm

open access: yesIET Power Electronics, EarlyView., 2023
This article presents a Fifteen‐level inverter topology that has a lesser number of switches (12) and can accommodate isolated DC sources. The total harmonic elimination (THD) of the proposed topology using genetic algorithm is within the IEEE 519 standards. Further, the fifteen‐level inverter is implemented in Hardware and firing pulses were generated

The stability analysis of the market price using Lambert function method

open access: yesLietuvos Matematikos Rinkinys, 2021
In this article we are going to analyze market price stability with different market intensity coefficient and delay argument values. Market price is described as a scalar differential equation with a delay argument.

Kepler’s Goat Herd: An exact solution to Kepler’s equation for elliptical orbits [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
A fundamental relation in celestial mechanics is Kepler’s equation, linking an orbit’s mean anomaly to its eccentric anomaly and eccentricity. Being transcendental, the equation cannot be directly solved for eccentric anomaly by conventional treatments;

Some updates to the method for calculation of parameters of bottom trawl system

open access: yesИзвестия ТИНРО, 2016
The method for calculation of geometric parameters of trawl system proposed by F.I. Baranov is analyzed. The calculation includes evaluation of spacer force and drag for all elements of trawl system and solution of transcendental equation to find a ...

On the Number of Solutions of a Transcendental Equation Arising in the Theory of Gravitational Lensing [PDF]

open access: yes, 2009
The equation in the title describes the number of bright images of a point source under lensing by an elliptic object with isothermal density. We prove that this equation has at most 6 solutions.
