"... Abstract. A basic idea of Dirichlet is to study a collection of interesting quantities {an}n≥1 by means of its Dirichlet series in a complex variable w: n≥1 ann−w. In this paper we examine this construction when the quantities an are themselves infinite series in a second complex variable s, arising ..."

Abstract. A basic idea of Dirichlet is to study a collection of interesting quantities {an}n≥1 by means of its Dirichlet series in a complex variable w: n≥1 ann−w. In this paper we examine this construction when the quantities an are themselves infinite series in a second complex variable s, arising from number theory or representation theory. We survey a body of recent work on such series and present a new conjecture concerning them. The object of this paper is to give a survey of a body of recent work applying methods from automorphic forms to problems in number theory. Generalizing this work, we shall also formulate a new conjecture concerning Langlands Lfunctions, which implies such results as the Lindelöf Hypothesis in twisted aspect. This

A BURGESSLIKE SUBCONVEX BOUND FOR TWISTED LFUNCTIONS
, 2005
"... Let g be a cuspidal newform (holomorphic or Maass) of arbitrary level and nebentypus, χ a primitive character of conductor q, and s a point on the critical line ℜs = 1. It is proved that 2 L(g ⊗ χ, s) ≪ε,g,s q 1 2 − 1 8 (1−2θ)+ε, where ε> 0 is arbitrary and θ = 7 is the current known approximati ..."

Let g be a cuspidal newform (holomorphic or Maass) of arbitrary level and nebentypus, χ a primitive character of conductor q, and s a point on the critical line ℜs = 1. It is proved that 2 L(g ⊗ χ, s) ≪ε,g,s q 1 2 − 1 8 (1−2θ)+ε, where ε> 0 is arbitrary and θ = 7 is the current known approximation towards the Ramanujan– 64 Petersson conjecture (which would allow θ = 0); moreover, the dependence on s and all the parameters of g is polynomial. This result is an analog of Burgess ’ classical subconvex bound for Dirichlet Lfunctions. In Appendix 2 the above result is combined with a theorem of Waldspurger and the adelic calculations of Baruch–Mao to yield an improved uniform upper bound for the Fourier coefficients of holomorphic halfintegral weight cusp forms.

This article gives an introduction to the multiple Dirichlet series arising from sums of twisted automorphic Lfunctions. We begin by explaining how such series arise from RankinSelberg constructions. Then more recent work, using Hartogs ’ continuation principle as extended by Bochner in place of such constructions, is described. Applications to the nonvanishing of Lfunctions and to other problems are also discussed, and a multiple Dirichlet series over a function field is computed in detail.

"... Abstract. The aim of this paper is to derive bounds on the critical line <s = 1 2 for Lfunctions attached to twists f ⊗ χ of a primitive cusp form f of level N and a primitive character modulo q that break convexity simultaneously in the s and q aspects.

Abstract. The aim of this paper is to derive bounds on the critical line <s = 1 2 for Lfunctions attached to twists f ⊗ χ of a primitive cusp form f of level N and a primitive character modulo q that break convexity simultaneously in the s and q aspects. If f has trivial nebentypus, it is shown that L(f ⊗ χ, s) (N sq)εN 45 (sq) 12 − 140, where the implied constant depends only on ε> 0 and the archimedean parameter of f. To this end, two independent methods are employed to show
