### Existence of solution for a system of quadratic diophantine equations / symmetric quadratic froms

This is just an extended comment, giving reformulation of the problem and reducing it to just $p-1$ unknowns and $p-1$ quadratic equations over the Gaussian integers. Consider the generating ...

### Generalization of the geometric series representation of the Kronecker delta for arbitrary lattices

The approach indicated by @AlexanderKalmynin is a good heuristic, for sure. Still, there is a somewhat larger context that may be more explanatory, depending on one's tastes. Namely, we can see that ...
