摘要
For a strictly pseucloconvex domain in a complex manifold we define a renormalized volume with respect to the approximately Einstein complete Kahler metric of Fefferman. We compute the conformal anomaly in complex dimension two and apply the result to derive a renormalized Chem-Gauss-Bonnet formula. Relations between renormalized volume and CR Q-curvature are also investigated. (c) 2007 Elsevier B.V. All rights reserved.
