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…

Solutions of quasi-geostrophic turbulence in multi-layered configurations

Sameerah Jamal

We consider quasi-geostrophic (Q-G) models in two- and three-layers that are useful in theoretical studies of planetary atmospheres and oceans. In these models, the streamfunctions…
