Embeddings of maximal tori in classical groups and explicit Brauer-Manin obstruction
Eva Bayer-Fluckiger, Ting-Yu Lee, Raman Parimala
Embeddings of maximal tori into classical groups over global fields of characteristic not 2 are the subject matter of several recent papers, with special attention to the Hasse pri…
