Published in 2021 at "Nonlinearity"

DOI: 10.1088/1361-6544/ac337e

Abstract: The study of hyperbolic waves involves various notions which help characterise how these structures evolve. One important facet is the notion of genuine nonlinearity, namely the ability for shocks and rarefactions to form instead of… read more here.

Published in 2020 at "Physical Review E"

DOI: 10.1103/physreve.101.036202

Abstract: We agree with the objection raised by Burde that the wave equation in our previous paper [Phys. Rev. E 90, 012907 (2014)PLEEE81539-375510.1103/PhysRevE.90.012907] was not derived in a consistent way. However, our paper contains an important… read more here.
