The pullback bundle is an example that bridges the notion of a pullback as precomposition, and the notion of a pullback as a Cartesian square. In that example, the base space of a fiber bundle is pulled back, in the sense of precomposition, above. The fibers then travel along with the points in the base space at which they are anchored: the ...
Pullback (differential geometry) This article is about pullback operations in differential geometry, in particular, the pullback of differential forms and tensor fields on smooth manifolds. For other uses of the term in mathematics, see pullback. Let be a smooth map between smooth manifolds and . Then there is an associated linear map from the ...
Pullback (category theory) In category theory, a branch of mathematics, a pullback (also called a fiber product, fibre product, fibered product or Cartesian square) is the limit of a diagram consisting of two morphisms f : X → Z and g : Y → Z with a common codomain. The pullback is written.
Briefly, a contravariant vector is a list of numbers that transforms oppositely to a change of basis, and a covariant vector is a list of numbers that transforms in the same way. Contravariant vectors are often just called vectors and covariant vectors are called covectors or dual vectors.
Price action trading. Price action is a method of analysis of the basic price movements to generate trade entry and exit signals that is considered reliable while not requiring the use of indicators. It is a form of technical analysis, as it ignores the fundamental factors of a security and looks primarily at the security's price history.

Vector bundle. The (infinitely extended) Möbius strip is a line bundle over the 1-sphere S1. Locally around every point in S1, it looks like U × R (where U is an open arc including the point), but the total bundle is different from S1 × R (which is a cylinder instead). In mathematics, a vector bundle is a topological construction that makes ...
