   Extractions: 5 References Traditionally, mathematics is built on set theory , and all objects studied in mathematics are ultimately sets and functions . It has been argued that category theory could provide a better foundation for mathematics. By analyzing precisely which properties of the category of sets and functions are needed to express mathematics, one arrives at the definition of topoi, and one can then formulate mathematics inside any topos. Of course, the category of sets forms a topos, but that is boring. In more interesting topoi, the axiom of choice may no longer be valid, or the law of excluded middle (every proposition is either true or false) may break down. It is thus of some interest to collect those theorems which are valid in all topoi, not just in the topos of sets. One may also work in a particular topos in order to concentrate only on certain objects. For instance

At that time the Weil conjectures were an outstanding motivation to research. As we now know, the route towards their proof, and other advances, lay in the construction of étale cohomology. With the benefit of hindsight, it can be said that algebraic geometry had been wrestling with two problems, for a long time. The first was to do with its points : back in the days of projective geometry it was clear that the absence of 'enough' points on an algebraic variety was a barrier to having a good geometric theory (in which it was somewhat like a compact manifold ). There was also the difficulty, that was clear as soon as

    Extractions: Where Geometry meets Dynamics Why would Topos Theory be helpful in Physics ? In physics there are a number of unanswered questions. Many efforts have been made by scientists/physicists to be able to answer those questions. Efforts which have lead to different paths of inquiry. In this web site I would like to focus on one particular path which unfortunately is not very trodden. The guiding principle of this path is the idea that the adoption of Topos theory in certain areas of physics , specifically Quantum Logic and Quantum Gravity might help shed light on how to solve some of the unanswered questions that arise in Physics. Unanswered questions and Topos Direction Isham 1999 Raptis 2001 What is a Physics Theory? The formulation of Quantum Theory rests on certain which, when seen from a general prospective, seems utterly unjustified to avoid such an unjustified conception , what is needed is an abstract generalization of a Physics Theory such that Quantum Mechanics is seen as a particular application of this general construct. Isham and Döring have shown that this abstraction can be achieved through Topos Theory in the following way: imagine we have a system S and we want to find a Physics Theory of S. First of all we need to decide what type of Physics Theory we want to define: either Classical or Quantum. Say we opt for a Classical Theory. It is then possible to construct a Topos t

    Extractions: Okay, you wanna know what a topos is? First I'll give you a hand-wavy vague explanation, then an actual definition, then a few consequences of this definition, and then some examples. I'll warn you: despite Chris Isham's work applying topos theory to the interpretation of quantum mechanics, and Anders Kock and Bill Lawvere's work applying it to differential geometry and mechanics, topos theory hasn't really caught on among physicists yet. Thus, the main reason to learn about it is not to quickly solve some specific physics problems, but to broaden our horizons and break out of the box that traditional mathematics, based on set theory, imposes on our thinking. Around 1963, Lawvere decided to figure out new foundations for mathematics, based on category theory. His idea was to figure out what was so great about sets, strictly from the category-theoretic point of view. This is an interesting project, since category theory is all about objects and morphisms. For the category of sets, this means SETS and FUNCTIONS. Of course, the usual axioms for set theory are all about SETS and MEMBERSHIP. Thus analyzing set theory from the category-theoretic viewpoint forces a radical change of viewpoint, which downplays membership and emphasizes functions. Even earlier, this same change of viewpoint was also becoming important in algebraic geometry, thanks to the work of Grothendieck on the Weil conjectures. So topos theory can be thought of as a merger of ideas from geometry and logic - hence the title of this book, which is an excellent introduction to topos theory, though not the easiest one:
