More on the Universal Equation for Efimov States [PDF]

open access: yesFew-body systems, 2019
Efimov states are a sequence of shallow three-body bound states that arise when the two-body scattering length is much larger than the range of the interaction. The binding energies of these states are described as a function of the scattering length and

Transcendental equations satisfied by the individual zeros of Riemann $\zeta$, Dirichlet and modular $L$-functions [PDF]

open access: yes, 2015
We consider the non-trivial zeros of the Riemann $\zeta$-function and two classes of $L$-functions; Dirichlet $L$-functions and those based on level one modular forms.

On Transcendental Systems of Equations [PDF]

open access: yesJournal of Siberian Federal University. Mathematics & Physics, 2021
Several types of transcendental systems of equations are considered: the simplest ones, special, and general. Since the number of roots of such systems, as a rule, is infinite, it is necessary to study power sums of the roots of negative degree. Formulas for finding residue integrals, their relation to power sums of a negative degree of roots and their

A harmonic instability analysis method for solving the zero and pole distributions of the transcendental equation

open access: yes电力工程技术, 2023
The distributed parameter model of the transmission line is a necessary premise for accurately analysing the harmonic instability of the wind farm. However, when the model is used for harmonic instability analysis, it causes difficulties in solving the ...

Phenomenological rate-independent uniaxial hysteretic models: A mini-review

open access: yesFrontiers in Built Environment, 2022
A great variety of phenomenological models has been proposed over the years to model rate-independent hysteretic forces in structural mechanics. The classification of such models is usually based on the type of equation that needs to be solved to ...

The solution of the problem of free circulation of circular arcs by numerical analytical boundary elements method [PDF]

open access: yesE3S Web of Conferences, 2020
The work is devoted to determining the natural frequencies and vibration modes of a circular arch using the numerical-analytical boundary elements method. A differential equation of the natural vibrations of the arch is obtained, a complete system of its
