Our method is representation theoretic and relies on the author’s recent results on global rational structures on automorphic representations. We show that the above period relations are intimately related to the field of definition of the global representation \r\n\r\n \r\n Π\r\n \\Pi\r\n \r\n\r\n under consideration. The new period relations we prove are in accordance with Deligne’s Conjecture on special values of \r\n\r\n \r\n L\r\n L\r\n \r\n\r\n-functions, and the author expects this method to apply to other cases as well.
