Lie Symmetry Analysis of a Nonlinear System Characterizing Endemic Malaria
Symmetry, 2022 In this paper, the integrability of a nonlinear system developing endemic Malaria was demonstrated using Prelle–Singer techniques. In addition, Lie symmetry techniques were employed to identify additional independent variables that led to the modification of the nonlinear model and the development of analytical solutions.

Scalar Lie point symmetries of the Standard Model with one or two real gauge singlets
Journal of High Energy PhysicsWe present a classification of all scalar Lie point symmetries of the Standard Model with one or two real gauge-singlet scalars (SM+S and SM+2S). By analyzing the associated field equations, we identify all realizable and inequivalent Lie point symmetry ...

Lie symmetry analysis of the Grad-Shafranov equation
, 2011 The theory of plasma physics offers a number of nontrivial examples of partial differential equations, which can be successfully treated with symmetry methods. We propose the Grad-Shafranov equation which may illustrate the reciprocal advantage of this interaction between plasma physics and symmetry techniques.

Lie symmetry analysis of a fractional Black-Scholes equation [PDF]
AIP Conference Proceedings, 2019 In 2000, Walter Wyss looked into the fractional version of the Black-Scholes equation for the first time. He gave a solution of the fractional Black-Scholes equation by using the Greens function [14]. In this paper, Lie symmetry analysis of a time fractional Black-Scholes equation with Riemann-Liouville derivative is performed.

Lie symmetry analysis of stochastic SIRS model
Communications in Mathematical Biology and Neuroscience, 2019 In this paper, we discuss the connection between Lie symmetry of a SIRS stochastic differential equations and its integrability. A derived determining equation is obtained and used to find the admitted Lie point symmetries of the stochastic model. A third dimensional system is reduced into a one dimensional to achieve a linear model by mean of Symmetry
