Alcune osservazioni sulle onde magnetoacustiche
Nel presente lavoro si fanno alcune osservazioni sulle onde magnetoacustiche. Esse, per quanto è a conoscenza dell'autore, non sono presenti nella vastissima letteratura sull'argomento; nonostante la loro semplicità, è sembrato di un qualche interesse segnalarle esplicitamente per il loro contenuto fisico. Specificatamente riguardano: l'effetto Doppler; la quantità di moto; il carattere di onde di condensazione; il carattere conservativo del campo di forza magnetica; l'equipartizione dell'energia....

Analysis of total variation flow and its finite element approximations
We study the gradient flow for the total variation functional, which arises in image processing and geometric applications. We propose a variational inequality weak formulation for the gradient flow, and establish well-posedness of the problem by the energy method. The main idea of our approach is to exploit the relationship between the regularized gradient flow (characterized by a small positive parameter , and the minimal surface flow [21] and the prescribed mean curvature flow [16]. Since our...
