Riemannian Spin Manifolds
摘要
We now extend our treatmentRiemannian spin manifold ofSpin manifold noncommutative geometric spaces from the finite case to the continuum. This generalizes spin manifoldsSpin manifold to the noncommutative world. The resulting spectral triplesSpectral triple (Chapter 5) form the key technical device in noncommutative geometry, and in the physical applications of Part 2 of this book in particular.
