Download or read book Supported Blow-Up and Prescribed Scalar Curvature on $S^n$ written by Man Chun Leung and published by American Mathematical Soc.. This book was released on 2011 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author expounds the notion of supported blow-up and applies it to study the renowned Nirenberg/Kazdan-Warner problem on $S^n$. When $n \ge 5$ and under some mild conditions, he shows that blow-up at a point with positive definite Hessian has to be a supported isolated blow-up, which, when combined with a uniform volume bound, is a removable singularity. A new asymmetric condition is introduced to exclude single simple blow-up. These enable the author to obtain a general existence theorem for $n \ge 5$ with rather natural condition.
