Modified Korteweg-de Vries equation as a system with benign ghosts
Autor: Smilga, Andrei
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)We consider the modified Korteweg-de Vries equation, uxxx + 6u2ux + ut = 0, and explore its dynamics in spatial direction. Higher x derivatives bring about the ghosts. We argue that these ghosts are benign, i.e., the ...
