一カ所、(the quadratic Gauss sum can also be evaluated by Fourier analysis as well as by contour integration)
と出てくるだけだ
ともかく、べき根とFourier analysisとの関係について、語って下さい

Gauss sum
History
In this case Gauss proved that G(χ) = p^1?2 or ip^1?2 for p congruent to 1 or 3 modulo 4 respectively (the quadratic Gauss sum can also be evaluated by Fourier analysis as well as by contour integration).

複素線積分
特に道がジョルダン曲線の場合の線積分を周回積分（しゅうかいせきぶん、英: contour integral）ということがある。
