Symmetry Analysis for a New Form of the Vortex Mode Equation
Mehdi Nadjafikhah, Ali Mahdipour--Shirayeh
Giving a new form of the vortex mode equation by a proper change of parameter, our aim is to analyze the point and contact symmetries of the new equation. Fundamental invariants an…
Symmetry of Quadratic Homogeneous Differential Systems
Mehdi Nadjafikhah, Ali Mahdipour-Shirayeh
In this paper, the symmetry group of a differential system of n quadratic homogeneous first order ODEs of n variables is studied. For this purpose, we consider the action of both p…
