| Jul 28, 2013 at 4:56 | comment | added | Steven | Sorry, I still do not quite see the relation between the derivation in that wikipedia article and the generalized theta function identity. Are you saying replacing the delta function by an exponential function in the step where we do the Fourier transformation of the lattice function will give the proof the generalized delta-function identity? | |
| Jul 28, 2013 at 1:08 | comment | added | Igor Rivin | @Steven: the wikipedia article I pointed at is describing exactly the content of the paper you were curious about (see the reference list at the end), and the Ewald theta function arises in that context. | |
