Construction of blow-up sequences for the prescribed scalar curvature equation on S n . II. Annular domains

Using the Lyapunov–Schmidt reduction method, we describe how to use annular domains to construct (scalar curvature) functions on S ⁿ (n ≥ 6), so that each one of them enables the conformal scalar curvature equation to have a blowing-up sequence of positive solutions. The prescribed scalar curvature function is shown to have C ^{n - 1, β} smoothness.
