comment Need numerical approximation for Fourier{max(0,f(x,y))} given Fourier{f(x,y)}
thank you, It does seem like there is no easy trick to actually gain computation time here. If by chance you know any example for a non linear operartion that does have some specific trick, I would love to hear about it.

@PavelM, thank you for pointing out the error, it seems I am lacking some theoretical background, do you have a good source on non linear transforms?

comment Rate of convergence for a many point object ( function or surface ).
do you have any document\article using these methods to determine the rate of convergence of something? ( post it as an aswer and I will accept it )

yes we may assume the operator is linear.
