Rankin三重积与量子混沌
Rankin Triple Products and Quantum Chaos
摘要:
在四元数代数的Eichler阶所产生的双曲平面模同余群和余紧格上,我们证明了三元组的Maass形式、全纯形式及其组合的显式Harris-Kudla型公式.这些公式将相应的Rankin三重积L-函数的中心值与一个平方三线性周期积分联系起来。假设这些L-值的次凸估计,我们证明了量子唯一遍历性,相关的林德洛夫假设意味着定量形式的QUE,与最佳速率。结合Berry/Hejhal随机波猜想,利用Iwaniec/Ivic/Jutila的次凸性结果和Kim-Shahidi关于对称立方体尖度的结果,证明了三阶矩在高能极限下的衰减.
英文摘要:
We prove explicit Harris-Kudla type formulas for triples of Maass forms, holomorphic forms, and combinations thereof, on the hyperbolic plane modulo congruence groups and co-compact lattices arising from Eichler orders of quaternion algebras. These formulas relate the central value of the corresponding Rankin triple product L-function to a squared trilinear period integral. Assuming subconvexity estimates for these L-values, we prove Quantum Unique Ergodicity on such quotients; the relevant Lindelof hypotheses imply a quantitative form of QUE, with an optimal rate. In connection with the Berry/Hejhal Random Wave conjecture, we prove decay of third moments in the high energy limit, making use of a subconvexity result of Iwaniec/Ivic/Jutila and Kim-Shahidi's result on cuspidality of the symmetric cube.
