A proof of the Landsberg-Schaar relation by finite methods. (arXiv:1810.06172v1 [math.NT])
来源于:arXiv
The Landsberg-Schaar relation is a classical identity between quadratic Gauss
sums, normally used as a stepping stone to prove quadratic reciprocity. The
Landsberg-Schaar relation itself is usually proved by carefully taking a limit
in the functional equation for Jacobi's theta function. In this article we
present a direct proof, avoiding any analysis. 查看全文>>
