Analytic characterization of stability islands on two point vortex systems
Gil M. Marques, Sílvio Gama, Fernando L. Pereira
In a system of point vortices, there exist regions of stability around each vortex, even if the system is chaotic. These regions are usually called stability islands and they have…

Tracking Point Vortices and Circulations via Advected Passive Particles: an Estimation Approach
Gil Marques, Marco Martins Afonso, Sílvio Gama
We present a novel method for estimating the circulations and positions of point vortices using trajectory data of passive particles in the presence of Gaussian noise. The method c…
