Higher Time Derivative Theories From Integrable Models
Bethan Turner
Higher Time Derivative Theories are generated by considering space-time rotated KdV and mKdV systems. These systems are then studied to see if/how instabilities, usually associated…

Higher time-derivative theories from space-time interchanged integrable field theories
Andreas Fring, Takano Taira, Bethan Turner
We compare a relativistic and a nonrelativistic version of Ostrogradsky's method for higher-time derivative theories extended to scalar field theories and consider as an alternativ…
