Default stability criteria
Maciej Matyka
Posts: n/a

I have to solve some specifical type of nonlinear (partial, second order) differential equation. Everything is ok with method, but problem is to define good stability conditions for it.

Equation is quite simple, but simple von Neumann criteria doesn't work properly.

If anybody have some time, take a look for that equation: I will be very gratefully for your help!

Please note, that we don't need full solution or anything like, that, just I don't know how to start with stability criterias in that equation!

Best Regards,

Maciej Matyka
