The Okubo-Weiss Criteria in Two-Dimensional Hydrodynamic and Magnetohydrodynamic Flows
B. K. Shivamoggi, G. J. F. van Heijst, L. P. J. Kamp
The Okubo [2]-Weiss [3] criterion is recast by using the 2D hydrodynamic Beltrami condition (Shivamoggi et al.[13]) that approximates the slow flow-variation ansatz imposed in its…

Motion of a Vortex Filament in the Local Induction Approximation: Reformulation of the Da Rios-Betchov Equations in the Extrinsic Filament Coordinate Space
B. K. Shivamoggi, G. J. F. van Heijst
In recognition of the highly non-trivial task of computation of the inverse Hasimoto transformation mapping the intrinsic geometric parameter space onto the extrinsic vortex filame…

Divorticity and Dihelicity In Two-Dimensional Hydrodynamics
B. K. Shivamoggi, G. J. F. van Heijst, J. Juul Rasmussen
A framework is developed based on the concepts of {\it divorticity} ($\equiv\nabla\times\bfo$, $\bfo$ being the vorticity) and $\textit{dihelicity} g \lp \equiv\bfv\cd…
