MathOverflow is a question and answer site for professional mathematicians.

Sheaves and presheaves are important structures at the intersection of logic and geometry.

Sheaves in Geometry and Logic

Topoi behave much like the category of sets and possess a notion of localization; they are a direct generalization of point-set topology. Since the introduction of sheaves into mathematics in the s, a major theme has been to study a space by studying sheaves on a space. This idea was expounded by Alexander Grothendieck by introducing the notion of a "topos". The main utility of this notion is in the abundance of situations in mathematics where topological heuristics are very effective, but an honest topological space is lacking; it is sometimes possible to find a topos formalizing the heuristic. A Grothendieck topos is a category C which satisfies any one of the following three properties.

There will be homework problems each week. Each class session shall start with a lecture, a short break, and then a session dedicated to the previous week's homework problems. The homework problems will appear on this site. Topos theory has many different guises. On one hand, a Grothendieck topos is a generalization in fact categorification of a topological space, a viewpoint which underpinned Grothendieck's own intuition on topoi, and aided his proof of one of the Weil conjectures.

 - Дэвид… Все пришли в смятение. Сьюзан шла вперед, повторяя это имя, ее глаза неотрывно смотрели на экран. - Дэвид! - воскликнула она, еле держась на ногах.  - О, Дэвид… как они могли… Фонтейн растерялся: - Вы знаете этого человека.

 - Чем же отличаются эти чертовы изотопы. Никто этого не знает? - Ответа он не дождался. Техники и все прочие беспомощно смотрели на ВР.

 Мистер Беккер, я был не прав. Читайте медленно и очень внимательно. Беккер кивнул и поднес кольцо ближе к глазам. Затем начал читать надпись вслух: - Q… U… 1…S… пробел… С, Джабба и Сьюзан в один голос воскликнули: - Пробел? - Джабба перестал печатать.  - Там пробел.

Он быстро подошел к ним и остановился в нескольких сантиметрах от дрожащего Чатрукьяна. - Вы что-то сказали. - Сэр, - задыхаясь проговорил Чатрукьян.  - ТРАНСТЕКСТ вышел из строя.
