Abstract

The branching problem for a couple of non-compatible Lie algebras and their parabolic subalgebras applied to generalized Verma modules was recently discussed in \cite{ms}. In the present article, we employ the recently developed F-method, \cite{KOSS1}, \cite{KOSS2} to the couple of non-compatible Lie algebras (\LieGtwo,so(7))({\LieGtwo},{so(7)}), and generalized conformal so(7){so(7)}-Verma modules of scalar type. As a result, we classify the \LieGtwo\gop\LieGtwo \cap \gop'-singular vectors for this class of so(7)so(7)-modules.
