Bookmark or Share- Pullback of a map - Mathematics Stack ExchangeThe first is a categorical pullback (think dual to a categorical pushout). The second is in the sense of induced maps, (think dual to a pushforward). Sometimes the two do sort of intersect, such as in pullback bundles. $\endgroup$ –

- Meaning of pullback - Mathematics Stack Exchange$\begingroup$ I am not that well-versed in category theory, but it looks like saying that the diagram commutes means that the composition of f and p1 always gives the same result as the composition of g and p2; if p1 is invertible, then this means g is the pullback of f by the composition of p2 and the inverse of p1, in something like the earlier sense (if all of the morphisms are functions ...
- Definition of pull back operation - Mathematics Stack ExchangeAlso look on the properties being used: first we use 1 and put the pullback inside the sum, then we use 2 and compose the coordinate functions of $\omega$ with $\varphi$, then we use 3 to write the pullback of that whole wedge product as the wedge product of the pullbacks and finally we use 4 to write the pullback of each differential of ...
- Definition of pullback. - Mathematics Stack ExchangeConcerning the difference between the pull-back of a vector field (page 134 of Guillemin and Pollack) and the pull-back of a differential form (page of 163 Guillemin and Pollack).
