Galilean geometry of motions
Mehdi Nadjafikhah, Ahmad-Reza Forough
In this paper we show that Galilean group is a matrix Lie group and find its structure. Then provide the invariants of special Galilean geometry of motions, by Olver's method of mo…

Self-equivalence 3rd order ODEs by time-fixed transformations
Mehdi Nadjafikhah, Ahmad Reza Forough
Let y''' = f(x, y, y', y'') be a 3rd order ODE. By Cartan equivalence method, we will study the local equivalence problem under the transformations group of time-fixed coordinates.
