摘要

We construct and give a complete classification of all the differential symmetry breaking operators \(\mathbb {D}_{\lambda , \nu }^{N,m}: C^\infty (S^3, \mathcal {V}_\lambda ^{2N+1}) \rightarrow C^\infty (S^2, \mathcal {L}_{m, \nu })\) , between the spaces of smooth sections of a vector bundle of rank \(2N+1\) over the 3-sphere \(\mathcal {V}_\lambda ^{2N+1} \rightarrow S^3\) , and a line bundle over the 2-sphere \(\mathcal {L}_{m, \nu } \rightarrow S^2\) in the special case \(|m| = N\) .
