On Transversally Elliptic Operators and the Quantization of Manifolds with f-Structure

Abstract: An f -structure on a manifold M is an endomorphism field ϕ ∈ Γ(M, End(T M )) such that ϕ 3 + ϕ = 0. Any f -structure ϕ determines an almost CR structure E 1,0 ⊂ T C M given by the +i-eigenbundle of ϕ. Using a compatible metric g and connection ∇ on M , we construct an odd first-order differential operator D, acting on sections of S = ΛE * 0,1 , whose principal symbol is of the type considered in [Fit09b]. In the special case of a CR-integrable almost S-structure, we show that when ∇ is the generalized Tanaka-W… Show more

“…In [14] it is proved that a CR-integrable almost S-manifold admits a canonical connection analogous to the Tanaka-Webster connection of a strongly pseudoconvex CR manifold. For the relationship between this connection and the ∂ b operator of the corresponding tangential Cauchy-Riemann complex, as well as an application of this relationship to defining an analogue of geometric quantization for almost S-manifolds, see [7].…”

“…We can fix the coefficients of ξ by requiring that ξ be the Hamiltonian vector field associated to the constant function 1, as is standard for Jacobi structures (see [15]). It is easy to see that (7) then immediately forces us to take ξ = α j ξ j ; that is, the coefficients b j are equal the constants α j . Thus, ξ is essentially determined by the almost S structure, although η is constrained only by the condition η(ξ) = 1, so the Jacobi structure we define below cannot be considered entirely canonical (as one might expect).…”
