Automorphic forms of higher order
arXiv:0802.0361 · doi:10.1112/jlms/jdp015
Abstract
In this paper a theory of Hecke operators for higher order modular forms is established. The definition of cusp forms and attached L-functions is extended beyond the realm of parabolic invariants. The role of representation theoretic methods is clarified and, motivated by higher order forms, new convolution products of L-functions are introduced.
