On singular Yamabe obstructions
Andreas Juhl, Bent Orsted
We discuss the singular Yamabe obstruction of a hypersurface in a four-dimensional general background. We derive various explicit formula for from t…
Residue families, singular Yamabe problems and extrinsic conformal Laplacians
Andreas Juhl, Bent Orsted
Let be a compact manifold with boundary and a defining function of . To these data, we associate natural conformally covariant polynomial one-parameter familie…
Shift operators, residue families and degenerate Laplacians
M. Fischmann, A. Juhl, B. Ørsted
We introduce new aspects in conformal geometry of some very natural second-order differential operators. These operators are termed shift operators. In the flat space, they are int…
Rigidity of conformal functionals on spheres
Niels Martin Moller, Bent Orsted
In this paper we investigate the nature of stationary points of functionals on the space of Riemannian metrics on a smooth compact manifold. Special cases are spectral invariants a…
