WebGenerally speaking, the Bochner-Technique is a method to relate the Laplace operator of a Riemannian manifold to its curvature tensor. It is often used to derive topological consequences from curvature conditions through analysis. This book appeared originally in 1988, and the new edition, under review here, is slightly expanded from the first. http://webbuild.knu.ac.kr/~yjsuh/proceedings/13th/%5B2%5D09Prowork_Itoh_1.pdf
