The Ambient Obstruction Tensor and Q-Curvature
C. Robin Graham, Kengo Hirachi
It is shown that the variational derivative of the integral of Branson's Q-curvature is the ambient obstruction tensor of Fefferman-Graham. A classification of irreducible conforma…

Conformally invariant powers of the Laplacian -- A complete non-existence theorem
A. Rod Gover, Kengo Hirachi
We show that on conformal manifolds of even dimension there is no conformally invariant natural differential operator between density bundles with leading part a power of…

Construction of boundary invariants and the logarithmic singularity of the Bergman kernel
Kengo Hirachi
This paper studies Fefferman's program \cite{F3} of expressing the singularity of the Bergman kernel, for smoothly bounded strictly pseudoconvex domains $Ω\subset\C^n$, in terms of…
