Orbital Normal Forms for a family of-zero Singularity

پژوهش‌های ریاضی, 2016
Consider a Dynamical system x'=F(x,µ) such that its linear part has a pair of imaginary eigenvalues and one zero eigenvalue (Hopf zero singularity). Recently, the simplest normal form for this singular system has been obtained by sl(2) Lie algebra theory

Normal forms of piecewise-smooth monodromic systems

Advances in Nonlinear Analysis
Normal form is an important tool in the study of bifurcations but, unlike those for smooth differential systems, normal forms for piecewise-smooth systems have difficulty with the near-identity transformation, which is constructed piecewise but needs to ...

Analyzing The Encountered Problems and Possible Solutions of Converting Relational Databases to Graph Databases

Journal of Advanced Research in Natural and Applied Sciences, 2022
Relational database management systems have been used for storing data for a long time.However, these systems are insufficient to analyze the large and complex structure of the data.

Quasi-periodic oscillations of a neuron equation with two delays

Моделирование и анализ информационных систем, 2011
The dynamics of a generalized impulse neuron equation with two delays is studied. A local analysis of a loss of stability for a nonzero equilibrium state has been made.

Normal form of double-Hopf singularity with 1:1 resonance for delayed differential equations

Nonlinear Analysis, 2019
In this manuscript, we provide a framework for the double-Hopf singularity with 1:1 resonance for general delayed differential equations (DDEs). The corresponding normal form up to the third-order terms is derived.

Normalization of equation with linear distributed delay

Моделирование и анализ информационных систем, 2009
Some properties of the dynamics of a differential equation with the linear distributed delay is studied. In critical cases, which all have an infinite dimension, special equations - normal forms - were built.

Periodic cycles in the Solow model with a delay effect

Mathematical Modelling and Analysis, 2019
The three natural modifications of the known mathematical macroeconomics model of macroeconomics are studied in which a delay factor is presumed. This led to the replacement of the ordinary differential equation, which cannot exhibit periodic cycles on ...
