A GL3 level analog of Selberg's result for S(t)

Abstract

Let π be a spherical cuspidal GL3 newform of prime level N and trivial central character, and define S(t,π)=π−1arg L(1/2+it,π). Assuming the generalized Riemann hypothesis for L(s,π), we establish an asymptotic formula for each fixed weighted moment of S(t,π) as N→∞, for fixed t>0. Consequently, under the same weights, S(t,π)/√(loglog N) converges in distribution to a centered Gaussian distribution of variance 1/(2π2). The key input is a weighted orthogonality formula derived from the Kuznetsov formula of prime level.

AB  - Let π be a spherical cuspidal GL_3 newform of prime level N and trivial central character, and define S(t,π)=π^−1arg L(1/2+it,π). Assuming the generalized Riemann hypothesis for L(s,π), we establish an asymptotic formula for each fixed weighted moment of S(t,π) as N→∞, for fixed t>0. Consequently, under the same weights, S(t,π)/√(loglog N) converges in distribution to a centered Gaussian distribution of variance 1/(2π^2). The key input is a weighted orthogonality formula derived from the Kuznetsov formula of prime level.
