Abstract

This paper studies the Prasad conjecture for the special orthogonal group SO3,3. Then we use the local theta correspondence between Sp4 and O(V) to study the Sp4-distinction problems over a quadratic field extension E/F and dimV=4 or 6. Thus we can verify the Prasad conjecture for a square-integrable representation of Sp4(E).
