Abstract

We obtain a strong bound on the second moment of the GL3GL_3 standard LL-function on the critical line. The method builds on the recent work of Aggarwal, Leung, and Munshi which treated shorter intervals. We deduce some corollaries including an improvement on the error term in the Rankin-Selberg problem, and on certain subconvexity bounds for GL3×GL2GL_3 \times GL_2 and GL3GL_3 LL-functions. As a byproduct of the method of proof, we also obtain an estimate for an average of shifted convolution sums of GL3GL_3 Fourier coefficients.
