Hello to everyone. I am new with this forum and I am asking help with PDE.(adsbygoogle = window.adsbygoogle || []).push({});

I have a linear PDE:

L f(x,y,t) = 0

where L is a second order linear operator depending on x, y, their partial derivatives, and t, but not on derivatives with respect to t. The question is: does this PDE in general admit steady state (time independent) solutions f(x,y)?

Thanks in advance.
