Pseudohermitian Curvatures on Bounded Strictly Pseudoconvex Domains in C2

In this paper, we present a formula for pseudohermitian curvatures on bounded strictly pseudoconvex domains in C2 with respect to the coefficients of adapted frames given by Graham and Lee in [3] and their structure equations. As an application, we will show that the pseudohermitian curvatures on strictly plurisubharmonic exhaustions of Thullen domains diverges when the points converge to a weakly pseudoconvex boundary point of the domain.
