Abstract
Let SO 2l be the special orthogonal group either split or quasisplit over a number field and 1 l n We compute the local integral where data are unramified derived from the global RankinSelberg construction for SO 2l × GL n In the general case the local integral is difficult to compute directly so instead it is transformed to an integral related to a construction for SO 2n+1×GL n which carries a Bessel model on SO 2n+1 For the quasisplit case when l = n − 1 we are able to compute the local integral by a modification of our recently introduced approach using invariant theory This leads to another proof of our result for 1 l n as well as a new proof of a known result regarding the unramified Bessel function
