Decomposition of a Tensor Product of a Higher Symplectic Spinor Module and the Defining Representation of sp(2n, C)
Journal of Lie Theory, Volume 17 (2007) no. 1, pp. 63-72
\def\p{{\frak p}} \def\s{{\frak s}} \def\C{{\Bbb C}} Let $L(\lambda)$ be the irreducible highest weight $\s\p(2n,\C)$-module with a highest weight $\lambda$, such that $L(\lambda)$ is an infinite dimensional module with bounded multiplicities, and let $F(\varpi_1)$ be the defining representation of $\s\p(2n,\C)$. In this article, the tensor product $L(\lambda)\otimes F(\varpi_1)$ is explicitly decomposed into irreducible summands. This decomposition may be used in order to define some invariant first order differential operators for metaplectic structures.
