How to transform the DKS equation to Fourier space

hunter151 · Aug 7, 2008

So I suppose my Fourier knowledge is a little bit rusty. Any help would be greatly appreciated.

How do they get from the original DKS equation to the Fourier space DKS equation (from eq 1 to eq 2)?

Thanks greatly for any help.

Just out of interest which DKS equation does this refer to ?
