Integral Moments of Automorphic L–functions

چکیده
We obtain second integral moments of automorphic L–functions on adele groups GL2 over arbitrary number fields, by a spectral decomposition using the structure and representation theory of adele groups GL1 and GL2. This requires complete reformulation of the notion of Poincaré series, replacing the collection of classical Poincaré series over GL2(Q) or GL2(Q(i)) with a single, coherent, global object that makes sense over a number field. This is the first expression of integral moments in adele-group-theoretic terms, distinguishing global and local issues, and allowing uniform application to number fields. When specialized to the field of rational numbers Q, we recover the classical results on moments.

Higher Integral Moments of Automorphic L-functions in Short Intervals
We consider the higher integral moments for automorphic L-functions in short intervals and give a proof for the conjecture of Conrey et al. under Generalized Riemann Hypothesis for automorphic L-function.
متن کاملOn tensor product $L$-functions and Langlands functoriality
In the spirit of the Langlands proposal on Beyond Endoscopy we discuss the explicit relation between the Langlands functorial transfers and automorphic $L$-functions. It is well-known that the poles of the $L$-functions have deep impact to the Langlands functoriality. Our discussion also includes the meaning of the central value of the tensor product $L$-functions in terms of the Langl...
متن کاملLower Bounds for Moments of Automorphic L-functions over Short Intervals
Let L(s, π) be the principal L-function attached to an irreducible unitary cuspidal automorphic representation π of GLm(AQ). The aim of the paper is to give a simple method to show the lower bounds of mean value for automorphic L-functions over short intervals.
متن کاملTwisted Moments of Automorphic L-functions
We study the moments of the symmetric power L-functions of primitive forms at the edge of the critical strip twisted by the square of the value of the standard L-function at the center of the critical strip. We give a precise expansion of the moments as the order goes to infinity. CONTENTS
متن کاملSubconvexity Bounds for Automorphic L–functions
We break the convexity bound in the t–aspect for L–functions attached to cuspforms f for GL2(k) over arbitrary number fields k. The argument uses asymptotics with error term with a power saving, for second integral moments over spectral families of twists L(s, f ⊗χ) by grossencharacters χ, from our previous paper [Di-Ga]. §0. Introduction In many instances, for cuspidal automorphic forms f on r...
