Refined blow-up criteria and global solutions for triangular cross-diffusion systems
Alexandre Bertolino
We study the Cauchy problem associated with a class of triangular cross-diffusion systems of Shigesada-Kawasaki-Teramoto type. We develop a self-contained well-posedness theory in…

Instantaneous Frequency Estimation in Noisy Multicomponent Signals with Interfering Modes Based on Prony Method and Spline Approximation
Basile Dubois-Bonnaire, Sylvain Meignen, Kévin Polisano
In this paper, we propose a novel estimator of the instantaneous frequencies (IFs) of the modes making up multicomponent signals (MCSs). We are particularly interested in dealing w…
