mathematics, a smooth functor is a type of functor defined on finite-dimensional real vector spaces. Intuitively, a smooth functor is smooth in the sense...

Differentiable manifold (redirect from Smooth manifold)
the manifold itself. The structure sheaf of M, denoted Ck, is a sort of functor that defines, for each open set U ⊂ M, an algebra Ck(U) of continuous functions...

Vector bundle (redirect from Smooth vector bundle)
bundles in a functorial manner. This is made precise in the language of smooth functors. An operation of a different nature is the pullback bundle construction...

Pushforward (differential) (redirect from Differential of a smooth map)
called the tangent map. In this way, T {\displaystyle T} is a functor. Given a smooth map φ : M → N and a vector field X on M, it is not usually possible...
