WebAmong the few exactly solvable problems in theoretical physics, the 2D (two-dimensional) Newtonian free fall problem in Euclidean space is perhaps the least known as compared to the harmonic oscillator or the Kepler–Coulomb problems. The aim of this article is to revisit this problem at the classical level as well as the quantum level, with a focus on its … Web26 de nov. de 2016 · In the case where K (u) = 1 u 2 + u, they were able to show that admits nonclassical symmetries that the original Equation does not.So, there is some evidence that the nonclassical symmetries of a PDE and a potential equation/equivalent system can be different (see also [] and references within).Although we will not address this question …
