Correlated dynamics of immune network and sl(3, R) symmetry algebra

Computational and Mathematical Biophysics
We observed the existence of periodic orbits in immune network under transitive solvable Lie algebra. In this article, we focus to develop condition of maximal Lie algebra for immune network model and use that condition to construct a vector field of ...

New interaction solutions and nonlocal symmetries for the (2 + 1)-dimensional coupled Burgers equation

Arab Journal of Basic and Applied Sciences, 2018
The nonlocal symmetries for the coupled (2 + 1)-dimensional Burgers system are obtained with the truncated Painlevé expansion method. The nonlocal symmetries can be localized to the Lie point symmetries by introducing auxiliary dependent variables.

Poisson-Lie symmetry and q-WZW model [PDF]

arXiv, 2005
We review the notion of (anomalous) Poisson-Lie symmetry of a dynamical system and we outline the Poisson-Lie symmetric deformation of the standard WZW model from the vantage point of the twisted Heisenberg double.

Lie point symmetry analysis of a second order differential equation with singularity

Journal of Mathematical Analysis and Applications, 2017
By using Lie symmetry methods, we identify a class of second order nonlinear ordinary differential equations invariant under at least one dimensional subgroup of the symmetry group of the Ermakov-Pinney equation. In this context, nonlinear superposition rule for second order Kummer-Schwarz equation is rediscovered.

Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States

Advanced Functional Materials, EarlyView.
The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.

Lie Symmetries of the Wave Equation on the Sphere Using Geometry

Dynamics
A semilinear quadratic equation of the form Aij(x)uij=Bi(x,u)ui+F(x,u) defines a metric Aij; therefore, it is possible to relate the Lie point symmetries of the equation with the symmetries of this metric. The Lie symmetry conditions break into two sets:
