The present thesis is devoted to the study both of strictly hyperbolic operators with low regularity coefficients and of the density-dependent incompressible Euler system. On the one hand, we show a priori estimates for a ...

Thirteen years after the first experimental observation of a Bose-Einstein condensed state (BEC) [1] in a dilute Bose gas of alkali atoms, the study of ultracold quantum systems has become a well established and active ...

Despite many efforts, the molecular mechanisms underlying the pathophysiology of neurodegenerative disorders have not been fully understood. Results published in literature highlight that different neurodegenerative diseases ...
