3-rd order partial differential equation |
Im looking for an physical plant ( mechanical, electrical, heat spreding
etc. ) whose mathematical model is:
partial differential equation of two independent variables (x,t)-(position,
time), THIRD order differential respect to time, and 2 and/or 4 order
derivatuves respect to x.
Anybody has any idea ??
??

What are you trying to do? Build an analog computer?

No, looking for an example for my pure mathematical research.
