Equivalence of categories between sheaves on $X$ and sheaves on a given base $B$ of $X$. In Remark 2.7.2 of Vakil's notes, he remarks that sheaves on $X$ and sheaves on a base $B$ are equivalent categories. Let the tw...
Start with a sheaf $\mathscr F$ on $X$, and then take $F:=\text{res }\mathscr F$ to get a sheaf on the base $B$. We'd like to extend this sheaf back to all of $X$ and see what happens. Well, now you should go look how this extension is constructed in Vakil. It is a large construction using classes o...

Sheave of sets, what does $\{f_i \} \mapsto \{f_i \mid_{U_i \cap U_j}\}$ mean? > ... for an open covering $U = \bigcup U_i$, an $I$-indexed family of functions $f_i : U_i \to \Bbb{R}, \ i \in I$, is an element of the ...
I think that these become clearer when rewritten with a different restriction symbol and with explicit indexing. We're sending the $I$-indexed set $(f_i)_{i\in I}$ to the $I^2$-indexed set $(f_i\upharpoonright U_i\cap U_j)_{i,j\in I}$, respectively the $I^2$-indexed set $(f_j\upharpoonright U_i\cap ...
