A note on the Kuramoto-Sivashinsky equation with discontinuity

  • Received: 25 July 2020 Accepted: 09 September 2020 Published: 22 October 2020
  • In this work we consider differential equations of the type $$\pm\, u^{(k)} = f(u), $$ and study the extinction profile of their solutions. Emphasis is placed on the special case $-u^{(4)} = sgn(u)$, which is related to the Kuramoto-Sivashinsky equation. In this case we describe in more detail the extinction phenomenon and prove a conjecture by Galaktionov and Svirshchevskii.
