The Global Theory of Smooth Functions,Our present goal is to extend the theory of smooth functions, developed on open subsets of ℝ. in Chapter 2, to arbitrary differentiable manifolds. Geometric topology becomes an essential feature.建筑师 发表于 2025-3-26 04:33:21
Lie Groups and Lie Algebras,Lie groups and their Lie algebras play a central role in geometry, topology, and analysis. Here we can only give a brief introduction to this fascinating topic.incite 发表于 2025-3-26 12:26:19
Multilinear Algebra and Tensors,Smooth functions, vector fields and 1-forms are . of fairly simple types. In order to handle higher order tensors, we will need some rather sophisticated multilinear algebra. The reader who is well grounded in the multilinear algebra of .-modules can skip ahead to Section 7.4, referring to the first three sections only as needed.jarring 发表于 2025-3-26 14:03:09
Forms and Foliations,In Section 4.5, we proved the vector field version of the Frobenius integrability theorem: . Γ(.) .(.) .. In this chapter, we develop an equivalent version of this theorem, stated in terms of the Grassmann algebra .*(.) of differential forms. Useful consequences of this point of view will be treated.SLAG 发表于 2025-3-26 18:21:05
