Summary: For a pseudo-Riemannian manifold $$X$$ and a totally geodesic hypersurface $$Y$$, we consider the problem of constructing and classifying all linear differential operators $$\mathcal{E}^i(X) \rightarrow\mathcal{E}^j(Y)$$ between the spaces of differential forms that intertwine multiplier representations of the Lie algebra of conformal vector fields. Extending the recent results in the Riemannian setting by the authors [Conformal symmetry breaking operators for differential forms on spheres. Singapore: Springer (2016; Zbl 1353.53002)], we construct such differential operators and give a classification of them in the pseudo-Riemannian setting where both $$X$$ and $$Y$$ are of constant sectional curvature, illustrated by the examples of anti-de Sitter spaces and hyperbolic spaces.
For the entire collection see [Zbl 1388.00033].
