Tangent space differential form
Webwords, ωxi is a linear functional on the space of tangent vectors at xi, and is thus a cotangent vector at xi.) In analogy to (3), the net work R γ ω required to move from a to b along the path γ is approximated by Z γ ω ≈ nX−1 i=0 ωxi(∆xi). (6) If ωxi depends continuously on xi, then (as in the one-dimensional case) one WebA one form θ sends p to θ(p) ∈ (TpM) ∗, which is called the contangent space. The elements of (TpM) ∗ are the linear functionals on TpM. If I start by fixing a vector field V, then I get a C∞ map p → θ(p)(Vp), that is, you evaluate the vector at p with the linear functional at p. Of course, you can do all this backwards.

I.e., dx^i is the ith coordinate function of the tangent space.
WebThe idea here is that each point p ∈ M has a vector space attached to it, namely its tangent space T p M, and the tangent bundle is the manifold formed by taking the disjoint union of all of these tangent spaces: T M = ⨆ p ∈ M T p M. While we can't talk about linearity with respect to the tangent bundle globally, we can impose linearity pointwise.
