Massive theta lifts
نویسندگان
چکیده
We use Poincare series for massive Maass-Jacobi forms to define a "massive theta lift", and apply it the examples of constant function modular invariant j-function, with Siegel-Narain as integration kernel. These integrals are deformations known one-loop string threshold corrections. Our lifts fall off exponentially, so some Rankin-Selberg finite without Zagier renormalization.

Theta-lifts of Maass Waveforms
Let O be an arbitrary order in an indeenite quaternion division algebra over Q. If O 1 is the group of elements in O with norm equal to 1, and H the complex upper half-plane, then X O := O 1 nH is a compact Riemann surface. Furthermore, let ? 0 (d) SL 2 (Z) be the Hecke congruence group of level d. Then X d := ? 0 (d)nH is a non-compact Riemann surface with nite volume. Let be the hyperbolic La...
متن کاملRegularized 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 کاملON THE (g,K)-COHOMOLOGY OF CERTAIN THETA LIFTS
It is well-known that one of the most important ways of constructing cohomology for an arithmetic quotient Γ\X, where X is the symmetric space associated with a semi-simple Lie group G with finite center and Γ is a discrete subgroup of G, is through the use of Matsushima’s formula, namely by exhibiting irreducible unitary representations with non-zero continuous cohomology which occur in L2(Γ\G...
متن کاملTheta lifts of Bianchi modular forms and applications to paramodularity
We explain how the work of Johnson-Leung and Roberts on lifting Hilbert modular forms for real quadratic fields to Siegel modular forms can be adapted to imaginary quadratic fields. For this, we use archimedean results from Harris, Soudry and Taylor and replace the global arguments of Roberts by the non-vanishing result of Takeda. As an application of our lifting result, we exhibit an abelian s...
متن کاملGlobal L - Packets for GSp ( 2 ) and Theta Lifts
Let F be a totally real number field. We define global L-packets for GSp(2) over F which should correspond to the elliptic tempered admissible homomorphisms from the conjectural Langlands group of F to the L-group of GSp(2) which are reducible, or irreducible and induced from a totally real quadratic extension of F . We prove that the elements of these global L-packets occur in the space of cus...
