CM values of automorphic Green functions on orthogonal groups over totally real fields

چکیده
Generalizing work of Gross–Zagier and Schofer on singular moduli, we study the CM values of regularized theta lifts of harmonic Whittaker forms. We compute the archimedian part of the height pairing of arithmetic special divisors and CM cycles on Shimura varieties associated to quadratic spaces over an arbitrary totally real base field. As a special case, we obtain an explicit formula for the norms of the CM values of those meromorphic modular forms arising as regularized theta lifts of holomorphic Whittaker forms. 2000 Mathematics Subject Classification: 14G35, 11F55, 11G18

Regularized Theta Lifts for Orthogonal Groups over Totally Real Fields
We define a regularized theta lift for orthogonal groups over totally real fields generalizing work of Borcherds. The lift takes harmonic ‘Whittaker forms’ to automorphic Green functions and weakly holomorphic Whittaker forms to meromorphic modular forms on orthogonal groups with zeros and poles supported on special divisors.
متن کاملSpecial values of Green functions at big CM points
We give a formula for the values of automorphic Green functions on the special rational 0-cycles (big CM points) attached to certain maximal tori in the Shimura varieties associated to rational quadratic spaces of signature (2d, 2). Our approach depends on the fact that the Green functions in question are constructed as regularized theta lifts of harmonic weak Maass forms, and it involves the S...
متن کاملCompanion Forms for Unitary and Symplectic Groups
We prove a companion forms theorem for ordinary n-dimensional automorphic Galois representations, by use of automorphy lifting theorems developed by the second author, and a technique for deducing companion forms theorems due to the first author. We deduce results about the possible Serre weights of mod l Galois representations corresponding to automorphic representations on unitary groups. We ...
متن کاملCOMPARISON RESULTS FOR CERTAIN PERIODS OF CUSP FORMS ON GL2n OVER A TOTALLY REAL NUMBER FIELD
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 ∆-function. If one wishes to compare these different techniques, then one needs to compare various automorphic periods attached to the symmetric cube transfer of ∆. Moti...
متن کاملHecke Characters and the K–theory of Totally Real and Cm Number Fields
Let F/K be an abelian extension of number fields with F either CM or totally real and K totally real. If F is CM and the BrumerStark conjecture holds for F/K, we construct a family of G(F/K)–equivariant Hecke characters for F with infinite type equal to a special value of certain G(F/K)–equivariant L–functions. Using results of Greither–Popescu [19] on the Brumer–Stark conjecture we construct l...
