Maass Forms and Their L-functions
We present examples of Maass forms on Hecke congruence groups, giving low eigenvalues on Γ0(p) for small prime p, and the first 1000 eigenvalues for Γ0(11). We also present calculations of the L-functions associated to the Maass forms and make comparisons to the predictions from random matrix theory.
متن کاملSubconvexity for Rankin-selberg L-functions of Maass Forms
This is a joint work with Yangbo Ye. We prove a subconvexity bound for Rankin-Selberg L-functions L(s, f⊗g) associated with a Maass cusp form f and a fixed cusp form g in the aspect of the Laplace eigenvalue 1/4 + k2 of f , on the critical line Res = 1/2. Using this subconvexity bound, we prove the equidistribution conjecture of Rudnick and Sarnak on quantum unique ergodicity for dihedral Maass...
متن کاملHeegner Divisors, L-functions and Harmonic Weak Maass Forms
Recent works, mostly related to Ramanujan’s mock theta functions, make use of the fact that harmonic weak Maass forms can be combinatorial generating functions. Generalizing works of Waldspurger, Kohnen and Zagier, we prove that such forms also serve as “generating functions” for central values and derivatives of quadratic twists of weight 2 modular L-functions. To obtain these results, we cons...
متن کاملComputation of Harmonic Weak Maass Forms
Harmonic weak Maass forms of half-integral weight are the subject of many recent works. They are closely related to Ramanujan’s mock theta functions, their theta lifts give rise to Arakelov Green functions, and their coefficients are often related to central values and derivatives of Hecke L-functions. We present an algorithm to compute harmonic weak Maass forms numerically, based on the automo...
متن کاملEffective Computation of Maass Cusp Forms
We study theoretical and practical aspects of high-precision computation of Maass forms. First, we compute to over 1000 decimal places the Laplacian and Hecke eigenvalues for the first few Maass forms on PSL(2,Z)\H. Second,we give an algorithm for rigorously verifying that a proposed eigenvalue together with a proposed set of Fourier coefficients indeed correspond to a true Maass cusp form. We ...
