Abstract

In this paper, we derive the sub-Riemannian version of the Kastler-KalauWalze type theorem and the Dabrowski-Sitarz-Zalecki type theorem for the twisted BCV spaces. We also compute the Connes conformal invariants for the twisted product, as well as the sub-Riemannian limits of the Connes conformal invariants for the twisted BCV spaces.

Key words： Scalar curvature; Sub-Riemannian limit; Conformal invarints; Twisted BCV spaces; Kastler-Kalau-Walze type theorems; Dabrowski-Sitarz-Zalecki type theorems
