I need to find the homogenous solution and fixed points to this pde. I have no idea how to proceed.

$$ \partial_t u = r u - (\partial_{xx}u +1)^2u - u^3 $$

It is second order non linear parital differential equation

  • $\begingroup$ It's not really a PDE unless there are derivatives involving more than one variable. All I see is spatial derivatives in $x$. $\endgroup$ Apr 28, 2016 at 13:37
  • $\begingroup$ sorry. i typed d_x instead of d_t $\endgroup$
