From Wikipedia, the free encyclopedia
Jump to: navigation search In category theory , a branch of mathematics , a Grothendieck topology is a structure on a category C which makes the objects of C act like the open sets of a topological space . Grothendieck topologies axiomatize the notion of an open cover . Using the notion of covering provided by a Grothendieck topology, it becomes possible to define sheaves on a category and their cohomology . This was first done in algebraic geometry and algebraic number theory by Alexander Grothendieck to define the ©tale cohomology of a scheme . It has been used to define other cohomology theories since then, such as l-adic cohomology flat cohomology , and crystalline cohomology . While Grothendieck topologies are most often used to define cohomology theories, they have found other applications as well, such as to John Tate 's theory of rigid analytic geometry There is a natural way to associate a category with a Grothendieck topology (a site ) to an ordinary topological space , and Grothendieck's theory is loosely regarded as a generalization of classical topology. Under meager point-set hypotheses, namely sobriety , this is completely accurate—it is possible to recover a sober space from its associated site. However simple examples such as the

Rigorous Trivialities
Grothendieck Topologies ... metric topology (usually on ), followed by point set topology . Then in graduate school, pretty much everyone gets an introduction to algebraic topology . However, it all really just studies sets with distinguished collections of subsets. There is, however, a more general version of topology, in fact, a way to put a topology onto a category due to, of course, Grothendieck So the first question is: how should topologies be defined? The traditional way is that, given a set , a topology is a collection of subsets satisfying the following properties: 2. If with an arbitrary index set, then 3. If then algebraic geometry When algebraic geometers work over the complex numbers, they get two topologies to work with, the classical topology, which has the small open sets that analysts and differential geometers love so much. Also, though, there is the Zariski topology Unfortunately, when algebraic geometers decide to work in positive characteristic, say in the algebraic closure of

Derived categories for dummies, Part I
Posted by urs
I am still trying to learn about derived categories, mostly using P. Aspinwall: D-Branes on Calabi-Yau Manifolds hep-th/0403166 First of all: what is a derived category anyway? The short answer is: The derived category D of any abelian category is the category of complexes in An abelian category is a category equipped with the necessary structure so as to make it possible to have sequences of morphisms in that category which form a complex . So in an abelian category we can have sequences d n n d n n d n n d n with all the n being objects and all the d n n being morphisms in is zero Furthermore, we can speak of the n-th

Grothendieck topologies and ideal closure operations - The integral closure and the submersive topology
Holger Brenner
University of Sheffield
Coauthors: Manuel Blickle This is a report on ongoing work relating closure operations for ideals and submodules like the radical, tight closure, integral closure, plus closure etc. to non-pure (in particular non-flat) Grothendieck theories. These closures are induced by sheafification in a suitable Grothendieck topology. The viewpoint of Grothendieck topologies does also yield concepts of stalks, of exactness, of module of global sections and of a cohomology theory. Date received: May 15, 2006 Atlas Conferences Inc.

Here is a table of recent seminars where you can find links to the slides and relevant notes where available. Here is a brief description of the content these talks.

02-May-07 (Leeds) Is the Ackermann function optimal?
A standard construction, originally due to Ackermann, produces a recursive function that is not primitive recursive. This can be relativized to produce a jump on the poset of degrees up to primitive recursive equivalence. What is there between a degree and its jump? Quite a lot.

Fake Projective Plane
This is a compact complex algebraic surface of general type having the same betti numbers as the projective plane. Such a surface was first imagined in connection with Severi's conjecture, which expects that the projective plane would be characterized only by its topological type, and, at first, it was completely unknown as to whether such a surface really exists or not. Since then, although the first knowledge of it was anything but substantial, the fake projective plane has attracted mathematician's curiosity even after S.-T. Yau's affirmative solution to Severi's conjecture because of the fact that, as well as being looking like a mysterious of the projective plane, it satisfies the equality in the famous Miyaoka-Yau inequality. The first example of such surfaces was discovered by Mumford in 1979, well-known nowadays as Mumford's fake projective plane . Amazing is not only his discovery itself but also the way of construction by means of dyadic uniformization , which realizes the surface in question as a discrete fixed-point free quotient of a certain symmetric domain in rigid analysis. The last fact can be seen in an interesting parallelism with the fact that any possible fake projective plane, being on the Miyaoka-Yau critical line, should be realized as a discrete fixed-point free quotient of the complex unit-ball by the procedure usually referred to as a uniformization in complex analysis.

Algebraic theory of tape-controlled attributed automata.28p.
ABSTRACT. Compositional theory of tape-controlled attributed automata is considered together with related developments in formal languages theory and algebra. It is proven that a class of finite automata defines a Grothendieck topology and the conditions are developed when a set of states of an automation determines a sheaf of sets of objects in the induced topological category. These two results are expected to be used in the proof that the induced fiber product of a Grothendieck topology is suitable for decomposition of tape- controlled attributed automata.

Okay, now the time has come to speak of many things: of topoi, glueballs, communication between branches in the many-worlds interpretation of quantum theory, knots, and quantum gravity. 1) Robert Goldblatt, Topoi, the Categorial Analysis of Logic, Studies in logic and the foundations of mathematics vol. 98, North-Holland, New York, 1984. If you've ever been interested in logic, you've got to read this book. Unless you learn a bit about topoi, you are really missing lots of the fun. The basic idea is simple and profound: abstract the basic concepts of set theory, so as to define the notion of a "topos", a kind of universe like the world of classical logic and set theory, but far more general! For example, there are "intuitionistic" topoi in which Brouwer reigns supreme - that is, you can't do proof by contradiction, you can't use the axiom of choice, etc.. There is also the "effective topos" of Hyland in which Turing reigns supreme - for example, the only functions are the effectively computable ones. There is also a "finitary" topos in which all sets are finite. So there are topoi to satisfy various sorts of ascetic mathematicians who want a stripped-down, minimal form of mathematics. However, there are also topoi for the folks who want a mathematical universe with lots of horsepower and all the options! There are topoi in which everything is a function of time: the membership of sets, the truth-values of propositions, and so on all depend on time. There are topoi in which everything has a particular group of symmetries. Then there are

Grothendieck spent the years 1953-55 at the University of Sao Paulo and then he spent the following year at the University of Kansas. However it was during this period that his research interests changed and they moved towards topology and geometry. ] the next period in Grothendieck's career is described as follows:- It is no exaggeration to speak of Grothendieck's years algebraic geometry , and him as its driving force. He received the Fields Medal in . In looking back at this period, one marvels at the generosity with which Grothendieck shared his ideas with colleagues and students, the energy he and his collaborators devoted to meticulous redaction, the excitement with which they set out to explore a new land.
