Hello,
Why are there two weights of size (..., half_modes, half_modes), and why is it applied to the :k_max/2 and -k_max/2:? I don't understand why not it is like that and not directly ":k_max". What am I missing about the implementation of the (R)FFT?

It applies the convolution theorem and performs a contraction of the (truncated) Fourier transform of the input with the learned weights of the spectral convolution. You can refer to the Fourier neural operator paper for the details.
