WebSheafification of Type valued presheaves #. We construct the sheafification of a Type valued presheaf, as the subsheaf of dependent functions into the stalks consisting of functions which are locally germs.. We show that the stalks of the sheafification are isomorphic to the original stalks, via stalk_to_fiber which evaluates a germ of a …
