设 G=ResE/FH,其中 H 是数域 F 上的连通约简群,E/F 是二次扩展。我们定义了 G 相对于 H 的自同构形式的正则化周期,并用交织周期来表达尖角艾森斯坦级数的正则化周期,这是标准交织算子的相对类似物。这导致了马斯-塞尔伯格关系的类比。正则化周期出现在连续谱对相对迹公式的贡献中。
Let G=ResE/FH, where H is a connected reductive group over a number field F and E/F is a quadratic extension. We define the regularized period of an automorphic form of G relative to H, and we express the regularized period of cuspidal Eisenstein series in terms of intertwining periods, which are relative analogues of the standard intertwining operators. This leads to an analogue of the Maass-Selberg relations. The regularized periods appear in the contribution of the continuous spectrum to the relative trace formula.
