Hopf Bifurcation Analysis for the van der Pol Equation with Discrete and Distributed Delays

Discrete Dynamics in Nature and Society, 2011
We consider the van der Pol equation with discrete and distributed delays. Linear stability of this equation is investigated by analyzing the transcendental characteristic equation of its linearized equation.

Inelastically scattering particles and wealth distribution in an open economy

, 2003
Using the analogy with inelastic granular gasses we introduce a model for wealth exchange in society. The dynamics is governed by a kinetic equation, which allows for self-similar solutions.

Relations between Solutions of Differential Equations and Small Functions

Abstract and Applied Analysis, 2012
We investigate relations between solutions, their derivatives of differential equation f(k)+Ak−1f(k−1)+⋯+A1f’+A0f=0, and functions of small growth, where Aj  (j=0,1,…,k−1) are entire functions of finite order.

On the roots of systems of transcendental equations

Issues of Analysis
Summary: The article is devoted to investigation of simple and multiple roots of systems of transcendental equations. It is shown that the number is related to the number of real roots of the resultant of the system. Examples for systems of equations are given.

More on the universal equation for Efimov states

, 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
