Gelbart and Piatetskii-Shapiro constructed various integral representations of Rankin–Selberg type for groups $G\,\times \,G{{L}_{n}}$ , where $G$ is of split rank $n$ . Here we show that their method can equally well be applied to the product ${{U}_{3}}\,\times \,G{{L}_{2}}$ , where ${{U}_{3}}$ denotes the quasisplit unitary group in three variables. As an application, we describe which cuspidal automorphic representations of ${{U}_{3}}$ occur in the Siegel induced residual spectrum of the quasisplit ${{U}_{4}}$ .
