摘要

We construct via generators and relations a generalized Weil representation for the split orthogonal group O-q (2n, 2n) over a finite field of q elements. Besides, we give an initial decomposition of the representation found. We also show that the constructed representation is equal to the restriction of the Weil representation to O-q (2n, 2n) for the reductive dual pair (Sp(2)(F-q), O-q (2n, 2n)) and that the initial decomposition is the same as the decomposition with respect to the action of Sp(2)(F-q).
