【 摘 要 】

We proof the Perelomov identity for arbitrary 2D lattices using Fourier transformation. We further generalize it to situations where the origin does not coincide with a lattice site and where the form of the exponential factor is reminiscent of magnetic wave functions in uniaxial rather than symmetric gauge.
