Abstract
We formulate a global Gan-Gross-Prasad conjecture for general spin groups. That is, we formulate a conjecture on a relation between periods of certain automorphic forms on GSpinn+1×GSpinn along the diagonal subgroup GSpinn and some L-values. To support the conjecture, we show that the conjecture holds for n=2 and 3 and for certain cases for n=4.
