In mathematics, a Grothendieck category is a certain kind of abelian category, introduced in Alexander Grothendieck's Tôhoku paper of in order to develop the machinery of homological algebra for modules and for sheaves in a unified manner.

The theory of these categories was further developed in Pierre Gabriel's seminal thesis in To every algebraic variety one can associate a. An Abelian category is a Grothendieck category if and only if it is equivalent to some quotient category of the type ${}_R \mathfrak{M} / \mathfrak{S}$.

In a Grothendieck category each object has an injective envelope, and for this reason Grothendieck categories are well suited for. The present book is a compendium or a collage of articles having Localisations and Grothendieck categories book do with the different facets of Grothendieck both as a hugely important and influential scholar and as an ultimately enigmatic individual with a remarkable history, including a past filled with childhood tragedy and strife, and a 5/5(1).

Grothendieck categories are locally presentable, and it's a more general fact that although locally presentable categories are only required to be cocomplete, the other axioms imply that they are in fact complete. This follows from the fact that locally presentable categories satisfy a very strong form of the adjoint functor theorem: any functor between locally presentable categories that.

The duality of Grothendieck categories with categories of modules over linearly compact rings is discussed in.

Abelian categories were introduced by Buchsbaum () (under the name of "exact category") and Grothendieck () in order to unify various cohomology theories.

At the time, there was a cohomology theory for sheaves, and a cohomology theory for groups. Alexandre Grothendieck, (born MaBerlin, Germany—died NovemSaint-Girons, France), German French mathematician who was awarded the Fields Medal in for his work in algebraic geometry.

After studies at the University of Montpellier (France) and a year at the École Normale Supérieure in Paris, Grothendieck received his doctorate from the University of Nancy.

The Grothendieck Construction and Gradings for Enriched Categories DaiTamaki∗† October25, Abstract The Grothendieck construction is a process to form a single category from a diagram of small categories.

In this paper, we extend the deﬁnition of the Grothendieck construction to File Size: KB. In category theory, a branch of mathematics, a Grothendieck topology is a structure on a category C that makes the objects of C act like the open sets of a topological space.A category together with a choice of Grothendieck topology is called a site.

Grothendieck topologies axiomatize the notion of an open the notion of covering provided by a Grothendieck topology, it becomes. The general theory of Grothendieck categories is presented. We systemize the principle methods and results of the theory, showing how these results can be used for studying rings and modules.

Some of these are not so standard outside of the. Using categorical techniques we obtain some results on localization and colocalization theory in Grothendieck categories with a set of small projective generators. In particular, we give a sufficient condition for such category to be semiartinian.

For semiartinian Grothendieck categories where every simple object has a projective cover, we obtain that every localizing subcategory is a by: 3. Grothendieck, "Technique de descente et théorèmes d'existence en géométrie algébrique, II" Sem. Bourbaki, Exp.

() Comments In the English literature, the Grothendieck functor is commonly called the Yoneda embedding or the Yoneda–Grothendieck embedding. This question is a few years old and it is perhaps a bit silly - how, after all, does one quantify or compare intellectual influence.

But I think Atiyah’s impact has been understated in the answers so far, so I feel compelled to chime in on his be. The ﬁrst proof of Grothendieck duality was given by Robin Hartshorne in [7], based on notes provided by Alexander Grothendieck in As the statement and proof require the use of derived categories, Jean–Louis Verdier’s ongoing (at the time) work was included in the ﬁrst two chapters of the book, and it was (as far as IFile Size: KB.

Although the statement of the Ax-Grothendieck theorem is already impressive in all of its forms, there is an interesting application to the study of cellular automata.

What these categories have in common is that (i) they behave very much like the category of sets, and (ii) they possess a good notion of localization.
