Well-posedness for a class of $n \times n$ hyperbolic systems and shock stability for the viscous approximation

Rahul Barthwal, Lilu Sahu

We establish the global well-posedness of weak solutions to the Cauchy problem for a broad class of multi-dimensional $n \times n$ Keyfitz-Kranzer type systems with homogeneous flux…

Energy consistent hyperbolic approximation for a class of fourth-order partial differential equations

Rahul Barthwal, Firas Dhaouadi, Christian Rohde

In this article, we propose a novel hyperbolic relaxation system for a general class of fourth-order nonlinear partial differential equations arising in the modelling of thin film…

Global Existence for a Class of Keyfitz--Kranzer Systems with Application to Thin-Film Flows

Rahul Barthwal, Philipp Öffner, Christian Rohde

We prove the existence of global weak entropy solutions for a class of non-symmetric Keyfitz-Kranzer type systems that includes lubrication models for thin-film flow. We identify a…
