Complex tangent bundle
WebJan 17, 2024 · Idea. A tangent bundle category is a category equipped with a “tangent bundle” endofunctor satisfying some natural axioms.. Usually these are called simply tangent categories, but on the nLab the page tangent category is about “the tangent category of a given category” constructed by abelianization. In other words, tangent … WebFor a smooth bundle this follows immediately from Proposition 7.3. The book [BT] is an excellent reference for this lecture, especially Chapter IV.

Websurfaces with nef tangent bundles. Theorem. — The smooth non algebraic compact complex surfaces with nef tangent bundles are precisely the following: (i) Non algebraic tori; (ii) Kodaira surfaces; (iii) Hopf surfaces. In the final section we give a classification of all non algebraic Kahler 3-folds. Theorem. In differential geometry, the tangent bundle of a differentiable manifold $${\displaystyle M}$$ is a manifold $${\displaystyle TM}$$ which assembles all the tangent vectors in $${\displaystyle M}$$. As a set, it is given by the disjoint union of the tangent spaces of $${\displaystyle M}$$. … See more One of the main roles of the tangent bundle is to provide a domain and range for the derivative of a smooth function. Namely, if $${\displaystyle f:M\rightarrow N}$$ is a smooth function, with $${\displaystyle M}$$ See more The tangent bundle comes equipped with a natural topology (not the disjoint union topology) and smooth structure so as to make it into a manifold in its own right. The dimension of $${\displaystyle TM}$$ is twice the dimension of $${\displaystyle M}$$ See more On every tangent bundle $${\displaystyle TM}$$, considered as a manifold itself, one can define a canonical vector field See more 1. ^ The disjoint union ensures that for any two points x1 and x2 of manifold M the tangent spaces T1 and T2 have no common vector. … See more A smooth assignment of a tangent vector to each point of a manifold is called a vector field. Specifically, a vector field on a manifold $${\displaystyle M}$$ is a smooth map $${\displaystyle V\colon M\to TM}$$ such that See more • Pushforward (differential) • Unit tangent bundle • Cotangent bundle See more • "Tangent bundle", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Wolfram MathWorld: Tangent Bundle See more
