Paralinearization and extended lifespan for solutions of the -SQG sharp front equation
Massimiliano Berti, Scipio Cuccagna, Francisco Gancedo +1
In this paper we paralinearize the contour dynamics equation for sharp-fronts of -SQG, for any , close to a circular vortex. This turns out to be a quas…

On asymptotic stability on a center hypersurface at the soliton for even solutions of the NLKG when
Scipio Cuccagna, Masaya Maeda, Federico Murgante +1
We extend the result M. Kowalczyk, Y. Martel, C. Muñoz, JEMS 2022, on the existence, in the context of spatially even solutions, of asymptotic stability on a center hypersurface at…
