On the structure of entropy dissipation and regularity for quasi-entropy solutions to 1d scalar conservation laws and to isentropic Euler system with

Fabio Ancona, Elio Marconi, Luca Talamini

In this paper, we first investigate quasi-entropy solutions to scalar conservation laws in several space dimensions. In this setting, we introduce a suitable Lagrangian representat…

Rectifiability of entropy productions for weak solutions of the 2D eikonal equation with supercritical regularity

Xavier Lamy, Elio Marconi

Weak solutions of the eikonal equation \begin{align*} |m|=1\text{ a.e. and }\mathrm{div}\: m =0\,, \end{align*} arise naturally as sha…

On the regularity of continuous solutions to multidimensional scalar conservation laws with bounded source

Fabio Ancona, Laura Caravenna, Alexander J. Cliffe +1

We prove the Hölder regularity of continuous isentropic solutions to multi-dimensional scalar balance laws when the source term is bounded and the flux satisfies general assumptio…

Liouville type theorem and kinetic formulation for 2x2 systems of conservation laws

Fabio Ancona, Elio Marconi, Luca Talamini

We study entropy solutions to systems of conservation laws. We show that, if a uniformly convex entropy exists, these solutions satisfy a pair of kin…

Well-posedness results for the Generalized Aw-Rascle-Zhang model

Elio Marconi, Laura V. Spinolo

We establish existence, uniqueness and stability results for the so-called Generalized Aw-Rascle-Zhang model, a second order traffic model introduced by Fan, Herty and Seibold. Our…

Nonlocal Generalized Aw-Rascle-Zhang model: well-posedness and singular limit

Elio Marconi, Laura V. Spinolo

We discuss a nonlocal version of the Generalized Aw-Rascle-Zhang model, a second-order vehicular traffic model where the empty road velocity is a Lagrangian marker governed by a tr…
