DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QARF/4/">On 
 some regularized nonlinear hyperbolic equations</a>\nby Billel Guelmame (E
 NS de Lyon) as part of Quebec Analysis and Related Fields Graduate Seminar
 \n\n\nAbstract\nIt is known that the solutions of nonlinear hyperbolic par
 tial differential equations develop discontinuous shocks in finite time ev
 en with smooth initial data. Those shock are problematic in the theoretica
 l study and in the numerical computations. To avoid these shocks\, many re
 gularizations have been studied in the literature. For example\, adding di
 ffusion and/or dispersion to the equation. In this talk\, we present and s
 tudy some non-diffusive and non-dispersive regularizations of the Burgers 
 equation and the barotropic Euler equations that have similar properties a
 s the classical equations.\n
