On the Periods of Automorphic Forms on Special Orthogonal Groups and the Gross–Prasad Conjecture

  • Atsushi Ichino
  • Tamutsu Ikeda


In this paper, we would like to formulate a conjecture on a relation between a certain period of automorphic forms on special orthogonal groups and some L-value. Our conjecture can be considered as a refinement of the global Gross–Prasad conjecture.
