Abstract:
In their work on a sharp compactness theorem for the Yamabe problem, Khuri, Marques and Schoen [J. Differential Geom. 81 (2009), 143–196] apply a refined blow - up analysis (what we call ‘ second order blow - up argument ’ in this article) to obtain highly accurate approximate solutions for the Yamabe equation. As for the conformal scalar curvature equation on $S^n$ with $n \ge 4$ , we examine the second order blow - up argument and obtain a refined estimate for a blow - up sequence near a simple blow - up point. The estimate involves the local effect from the Taylor expansion of the scalar curvature function, the global effect from other blow - up points, and the balance formula as expressed in the Pohozaev identity in an essential way.References
