Lie symmetry analysis of the Hanta-epidemic systems

Journal of Mathematics and Computer Science, 2017
Summary: We consider a model for the fatal Hanta-virus infection among mice. Lie symmetry analysis is applied to find general solutions to Hanta-virus model, which is also known as Abramson-Kenkre model. Besides the solution for the version with derivatives of fractional order, we investigate the model also by using the Lie symmetry method.

Lie Symmetry Analysis on Benjamin-Ono Equation

Journal of Physics: Conference Series, 2020
Abstract Benjamin-Ono Equation are significantly important in describes the one-dimensional internal waves in deep water. Because of its significance, Lie symmetry reduction were chosen to reduce the equation and hence solve the equation. Lie symmetry analysis is one of the powerful methods to solve partial differential equation.

Group classification of the Sachs equations for a radiating axisymmetric, non-rotating, vacuum space-time [PDF]

, 2006
We carry out a Lie group analysis of the Sachs equations for a time-dependent axisymmetric non-rotating space-time in which the Ricci tensor vanishes.

RENORMALIZATION GROUP SYMMETRY AND SOPHUS LIE GROUP ANALYSIS [PDF]

International Journal of Modern Physics C, 1995
We start with a short discussion of the content of a term Renormalisation Group in modern use. By treating the underlying solution property as a reparametrisation symmetry, we relate it with the self-similarity symmetry well-known in mathematical physics and explain the notion of Functional Self-similarity.

Lie symmetry analysis and invariant solutions for (2+1) dimensional Bogoyavlensky-Konopelchenko equation with variable-coefficient in wave propagation

Journal of Ocean Engineering and Science, 2022
This work aims to present nonlinear models that arise in ocean engineering. There are many models of ocean waves that are present in nature. In shallow water, the linearization of the equations requires critical conditions on wave capacity than it make ...

Lie symmetry analysis of conformable differential equations

AIMS Mathematics, 2019
In this paper, we construct a proper extension of the classical prolongation formula of point transformations for conformable derivative. This technique is illustrated and employed to construct a symmetry group admitted by a conformable ordinary and partial differential equations.

Non-simply-laced Lie algebras via F theory strings [PDF]

, 2010
In order to describe the appearance in F theory of the non--simply--laced Lie algebras, we use the representation of symmetry enhancements by means of string junctions.
