Riemannian Topology and Geometric Structures on Manifolds

Format: Hardcover Language: English Format: PDF / Kindle / ePub Size: 10.07 MB Downloadable formats: PDF Thurston's idea regarding 3-manifolds originated from an interesting fact about 2-manifolds that does tie in with geometric properties such as curvature. The authors do a good job of pretending like you don't have to know anything about algebraic topology but like I stated in the previous paragraph I couldn't resist googling because without getting some precursory knowledge it...
