Helmholtz equation:##\nabla^2 u=-ku## is the same form of ##\nabla^2 u=f##.
So is helmholtz equation a form of Poisson Equation?

yungman said:Thanks for the reply, I understand the difference between the two. But Helmholtz is also in form of Poisson, only when ##f=-k\nabla^2 u##. So, can I say Helmholtz is a subset or one form of Poission Equation?
Thanks

FWIW, sure, go ahead.
