Sheaves/Presheaves as Contravariant Functors, Kernel Presheaf is a Sheaf
Harpreet Bedi2013/08/27 に公開
There are two slides, in the first slide we talk about Presheaves as contravariant functors, talk about equalizer condition, sheafification and in the second slide we talk about Image and Coker presheag

Hi, at the end of the video (around 12:45) - if you manage to lift s_1 and s_2 to G(U), doesn't it give you a unique projection to G(U)/Im(U)? Isn't the problem with coimage not being sheaf more related to the fact that s_1 and s_2 in G(U_1) and G(U_2) don't neccessarily need to agree on the intersection of U_1 and U_2??
