这篇文章源自我在“斯里尼瓦萨·拉马努金的遗产”会议上的演讲,其中我谈到了一些证明附加到拉马努金 \Delta 函数的对称立方 L 函数的特殊值的代数结果的技术。如果希望比较这些不同的技术,则需要比较附加到 Delta 的对称立方体传递的各种自同构周期。受此问题的启发,在本文中,我们提供了 Whittaker-Betti 周期、Shalika-Betti 周期以及附加到全实数域上的 GL(2n) 给定上同调尖头自守表示的某些相对周期的比较结果。
This article grew out of my talk in "The Legacy of Srinivasa Ramanujan" conference where I spoke about some techniques to prove algebraicity results for the special values of symmetric cube L-functions attached to the Ramanujan \Delta-function. If one wishes to compare these different techniques, then one needs to compare various automorphic periods attached to the symmetric cube transfer of \Delta. Motivated by this problem, in this article we provide comparison results for Whittaker-Betti periods, Shalika-Betti periods and certain relative periods attached to a given cohomological cuspidal automorphic representation of GL(2n) over a totally real number field.
