Approximate conditions admitted by classes of the Lagrangian $L = \frac{1}{2} (- u^{'2} + u^{2}) + ε^{i} G_{i} (u, u^{'}, u^{''})$

Sameerah Jamal, Nkosingiphile Mnguni

We investigate a class of Lagrangians that admit a type of perturbed harmonic oscillator which occupies a special place in the literature surrounding perturbation theory. We establ…

Nonlocal Representation of the $s l (2, R)$ Algebra for the Chazy equation

Andronikos Paliathanasis, Sameerah Jamal, P. G. L. Leach

A demonstration of how the point symmetries of the Chazy Equation become nonlocal symmetries for the reduced equation is discussed. Moreover we construct an equivalent third-order…
