Results Related to Prescribing Pseudo-Hermitian Scalar Curvature

Abstract: In this paper, we consider the problem of prescribing pseudo-Hermitian scalar curvature on a compact strictly pseudoconvex CR manifold M. Using geometric flow, we prove that for any negative smooth function f we can prescribe the pseudo-Hermitian scalar curvature to be f, provided that dim M = 3 and the CR Yamabe invariant of M is negative. On the other hand, we establish some uniqueness and non-uniqueness results on prescribing pseudo-Hermitian scalar curvature.

“…For the case R θ 0 > 0, Chang, Chiu, and Wu [8] proved the convergence when M is spherical and n = 1 and θ 0 is torsion-free. For general n, the author proved in [27] the long time existence for the case when R θ 0 > 0, and the convergence when M is the CR sphere. As a generalization of CR Yamabe problem, one can consider prescribing CR Webster scalar curvature problem: given a function f on a CR manifold (M, θ 0 ), we want to find a contact form θ conformal to θ 0 such that its Webster scalar curvature R θ = f .…”

“…We are interested in the following question: can we find a contact form θ conformal to θ 0 such that its Webster scalar curvature R θ = f ? This has been studied in [9,11,14,16,23,24,25]. When f is constant, this is the CR Yamabe problem, which was solved by Jerison and Lee in [18,19,20], and by Gamara and Yacoub in [13,15].…”

“…As an analogy of the Nirenberg's problem, we ask the following question: can we find a contact form θ conformal to θ 0 such that its Webster scalar curvature R θ = f ? This has been studied in [9,13,14,16,23,25,26]. Using the Webster scalar curvature flow (see (2.1) below) which is a generalization of the CR Yamabe flow (see [15]), we have proved in [18] and [19] the following: …”
