L -functions of automorphic forms and combinatorics: Dyck paths

Source abstract

We give a combinatorial interpretation for the positive moments of the values at the edge of the critical strip of the L -functions of modular forms of G L ( 2 ) and G L ( 3 ) . We deduce some results about the asymptotics of these moments. We extend this interpretation to the moments twisted by the eigenvalues of Hecke operators.
