Journal ArticleDOI

Spectral zeta functions for the quantum rabi models

TL;DR: In this paper, the authors introduced the Hurwitz-type spectral zeta functions for the quantum Rabi models, and gave their meromorphic continuation to the whole complex plane with only one simple pole at $s=1$.
Journal ArticleDOI

Relative trace formulas and subconvexity estimates for $L$-functions of Hilbert modular forms

TL;DR: In this paper, an explicit version of the relative trace formula on PGL(2) over a totally real number field for the toral periods of Hilbert cusp forms along the diagonal split torus is presented.
Journal ArticleDOI

Asymptotic behaviors of means of central values of automorphic L-functions for GL(2)

TL;DR: In this paper, a relative trace formula for periods of automorphic forms along a split torus in GL ( 2 ) was presented, from a square-free level case to an arbitrary level case.
Journal ArticleDOI

An explicit trace formula of Jacquet-Zagier type for Hilbert modular forms

TL;DR: In this paper, an exact formula of the average of adjoint L-functions of holomorphic Hilbert cusp forms with a fixed weight and a square-free level was given.
Journal ArticleDOI

Regularized periods of automorphic forms on $gl(2)$

TL;DR: In this paper, the authors studied regularized periods of cusp forms and Eisenstein series on $GL(2)$ introduced by Masao Tsuzuki, and showed that the regularization of the series is beneficial.
