Dynamical systems theory of cellular reprogramming

open access: yesPhysical Review Research, 2022
In cellular reprogramming, almost all epigenetic memories of differentiated cells are erased by the overexpression of a few genes, resulting in regaining pluripotency, the potential for differentiation.

An Overview of the Hamilton–Jacobi Theory: the Classical and Geometrical Approaches and Some Extensions and Applications

open access: yesMathematics, 2021
This work is devoted to review the modern geometric description of the Lagrangian and Hamiltonian formalisms of the Hamilton–Jacobi theory. The relation with the “classical” Hamiltonian approach using canonical transformations is also analyzed ...

The modal sensitivity, robustness and roughness of dynamic systems (review article) [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2021
The review focuses on the development of theories of sensitivity and modal sensitivity, robustness and roughness of dynamic systems. In modern theory of dynamic systems and automatic control systems, there is a need to study the properties of sensitivity,

Dimension reduction of dynamical systems on networks with leading and non-leading eigenvectors of adjacency matrices

open access: yesPhysical Review Research, 2022
Dimension reduction techniques for dynamical systems on networks are considered to promote our understanding of the original high-dimensional dynamics.

On the birth of limit cycles for non-smooth dynamical systems [PDF]

open access: yes, 2014
The main objective of this work is to develop, via Brower degree theory and regularization theory, a variation of the classical averaging method for detecting limit cycles of certain piecewise continuous dynamical systems.

Time-averaging axion-like interacting scalar fields models

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this paper, we study a cosmological model inspired in the axionic matter with two canonical scalar fields $$\phi _1$$ ϕ 1 and $$\phi _2$$ ϕ 2 interacting through a term added to its potential. Introducing novel dynamical variables, and a dimensionless

Dark Type Dynamical Systems: The Integrability Algorithm and Applications

open access: yesAlgorithms, 2022
Based on a devised gradient-holonomic integrability testing algorithm, we analyze a class of dark type nonlinear dynamical systems on spatially one-dimensional functional manifolds possessing hidden symmetry properties and allowing their linearization on

Double field theory at SL(2) angles

open access: yesJournal of High Energy Physics, 2017
An extended field theory is presented that captures the full SL(2) × O(6, 6 + n) duality group of four-dimensional half-maximal supergravities. The theory has section constraints whose two inequivalent solutions correspond to minimal D = 10 supergravity ...

Synchronization of dissipative dynamical systems driven by non-Gaussian Lévy noises [PDF]

open access: yes, 2009
Dynamical systems driven by Gaussian noises have been considered extensively in modeling, simulation, and theory. However, complex systems in engineering and science are often subject to non-Gaussian fluctuations or uncertainties.

Discrete Dynamical Systems: A Brief Survey [PDF]

open access: yes, 2018
Dynamical system is a mathematical formalization for any fixed rule that is described in time dependent fashion. The time can be measured by either of the number systems - integers, real numbers, complex numbers.
