Definition

A generalization of the (Arthur–Selberg) trace formula that compares integrals of kernel functions over subgroups or quotients—periods of automorphic forms—leading to identities that relate relative (period) sums to spectral data; used to link automorphic representations to arithmetic quantities such as central L-values and periods.
