This invaluable book contains selected papers of Prof Chuan-Chih Hsiung, renowned mathematician in differential geometry and founder and editor-in-chief of a unique international journal in this field, the Journal of Differential Geometry.During the period of 1935–1943, Prof Hsiung was in China working on projective differential geometry under Prof Buchin Su. In 1946, he went to the United States, where he gradually shifted to global problems. Altogether Prof Hsiung has published about 100 research papers, from which he has selected 64 (in chronological order) for this volume.Contents:Projective Differential Geometry of a Pair of Plane CurvesA Projective Invariant of a Certain Pair of SurfacesAffine Invariants of a Pair of HypersurfacesA Theorem on Surfaces with a Closed BoundarySome Uniqueness Theorem on Riemannian Manifolds with BoundaryOn the Group of Conformal Transformations of a Compact Riemannian ManifoldMinimal Immersions in Riemannian SpheresA Remark on Pinched Manifolds with BoundaryNonexistence of a Complex Structure on the Six-SphereSome Conditions for a Complex Structureand other papersReadership: Researchers in differential geometry.Key Features:The advanced textbook addresses a broader audience of Master degree students than existing literature dedicated to more specialized scientistsThe advanced textbook might be purchased by non-specialists, such as MDs who want to follow the evolution of modern medicineThe global field of nucleotide-based therapies and nucleotide delivery are presented in this comprehensive textbook in simple words, giving easy access to key concepts and technologiesThe textbook also aims at helping non-specialized scientists choose an adequate gene transfer and/or gene therapy strategy
