Another Approach to Juhl ’ s Conformally Covariant Differential Operators from S n to S n −

چکیده
A family (Dλ)λ∈C of differential operators on the sphere S n is constructed. The operators are conformally covariant for the action of the subgroup of conformal transformations of S which preserve the smaller sphere Sn−1 ⊂ S. The family of conformally covariant differential operators from S to Sn−1 introduced by A. Juhl is obtained by composing these operators on S and taking restrictions to Sn−1.

Conformally Covariant Differential Operators: Properties and Applications
We discuss conformally covariant differential operators, which under local rescalings of the metric, δσg μν = 2σg , transform according to δσ∆ = r∆σ+(s−r)σ∆ for some r if ∆ is s th order. It is shown that the flat space restrictions of their associated Green functions have forms which are strongly constrained by flat space conformal invariance. The same applies to the variation of the Green fun...
متن کاملRecurrent metrics in the geometry of second order differential equations
Given a pair (semispray $S$, metric $g$) on a tangent bundle, the family of nonlinear connections $N$ such that $g$ is recurrent with respect to $(S, N)$ with a fixed recurrent factor is determined by using the Obata tensors. In particular, we obtain a characterization for a pair $(N, g)$ to be recurrent as well as for the triple $(S, stackrel{c}{N}, g)$ where $stackrel{c}{N}$ is the canonical ...
متن کاملTwistor Spinors on Lorentzian Manifolds, Cr-geometry and Feeerman Spaces
The paper deals with twistor spinors on Lorentzian manifolds. In particular , we explain a relation between a certain class of Lorentzian twistor spinors and the Feeerman spaces of strictly pseudoconvex spin manifolds which appear in CR-geometry. Let (M n;k ; g) be a n-dimensional smooth semi-Riemannian spin manifold of index k with the spinor bundle S. There are two conformally covariant diffe...

We will show that in the conformal class of the standard metric gSn on Sn, the scaling invariant functional g (S n) 2m n n R Sn Q2m;gd g maximizes at gSn when n is odd and m = n+1 2 or n+3 2 . For n odd and m n+5 2 , gSn is not stable and the functional has no local maximizer. Here Q2m;g is the 2mth order Q-curvature. 1.
