 Dec19 comment Difference between a stalk of a sheaf and a fiber of a vector bundle Thank you very much. :-) Dec19 comment Difference between a stalk of a sheaf and a fiber of a vector bundle Thanks ! Can you tell me how the fibre of a bundle is a limit in the general sense of category theory ? Idon"t understand this sentence : it is just the pullback of the bundle along the inclusion of a point. Thanks a lot. Dec19 awarded Scholar Dec19 comment Difference between a stalk of a sheaf and a fiber of a vector bundle Ok, i did it. Thank you. :) Dec19 accepted Difference between a stalk of a sheaf and a fiber of a vector bundle Dec19 comment Difference between a stalk of a sheaf and a fiber of a vector bundle Thank you very much @Zhen Lin. Can you tell me please, if it's true that the fiber $E_x = \pi^{-1} ( x )$ of a vector bundle $\pi : E \to X$ can be defined as the direct limit of maps $U \to E_{U} = \pi^{-1} ( U )$ like the stalk of a sheaf $\mathcal{F}_x$ ? In this case, what is the direct system which define this direct limit ? Thanks a lot.
