Category:Topology - Wikipedia, the free encyclopedia In mathematics, topology is a branch of geometry concerned with the study of topological spaces. Elementary properties of topological spaces are discussed in general topology. (The term topology is also used for a set of open sets used to define topological spaces) en.wikipedia.org /wiki/Category:Topology

defs.txt category theory The study of abstracted collections of mathematical objects, such as the category of sets or the category of vector spaces, together with abstracted operations sending one object to another, such as the collection of functions from one set to another or linear transformations from one vector space to another. Topology Glossary Mainly extracted from (a) UC Davis Math:Profile Glossary (http://www.math.ucdavis.edu/profiles/glossary.html) by Greg Kuperberg (http://www.math.ucdavis.edu/profiles/kuperberg.html), and (b) Topology Atlas Glossary (http://www.achilles.net/~mtalbot/TopoGloss.html). An early result in topology states that every closed 3-manifold (closed meaning that the manifold is finite and connected but has no boundary) has a Heegaard splitting and a resulting description in terms of a Heegaard diagram, which describes how the two handlebodies are glued together. www.ornl.gov /sci/ortep/topology/defs.txt

54: General topology Topology is the study of sets on which one has a notion of "closeness" -- enough to decide which functions defined on it are continuous. Thus a general theme in topology is to test the extent to which the axioms force the kind of structure one expects to use and then, as appropriate, introduce other axioms so as to better match the intended application. In particular, there are questions about topology which can be reduced to questions of set theory, whose answer then depends on the axioms of set theory chosen. www.math.niu.edu /~rusin/known-math/index/54-XX.html

IntroductionEssay In algebraic topology, every topological space was assigned a series of algebras and it was shown, in a technical sense, that two spaces are the same if (and only if) their algebras are the same. The study of topology also has an illustrious history: on a basic level it is mankind's attempt to model the physical world in which we all move. But the categories associated with locales, the so-called sheaf categories are, if you like, the strongest known: all of mathematics can be carried out in the category of sheaves on a locale. mcs.open.ac.uk /cft36/IntroductionEssay.htm

Topology Seminar It follows that the exponential $^X in the category of spaces or locales is important, since it represents the topology on X - the points of $^X are the opens on X. q It has long been known that the locale exponential $^X exists if and only if X is exponentiable (i.e. Point-free topology is a part of this area, and consist of the study of certain lattices called frames. A space X is called exponentiable if such a suitable topology exists on the set continuous maps from X to Y for every space Y. It is well-known that a Hausdorff space is exponentiable if and only if it is locally compact, and that in this case the exponential topology is the compact-open topology. www.cs.bham.ac.uk /research/events/topology-seminar/topology.html

Category Theory For it is in his thesis that Lawvere proposed the idea of developing the category of categories as a foundation for category theory, set theory and, thus, the whole of mathematics, as well as using categories for the study of theories, that is the logical aspects of mathematics. Category theory reveals that many of these constructions are in fact special cases of objects in a category with what is called a "universal property". On the one hand, it is certainly the task of philosophy to clarify the general epistemological status of category theory and, in particular, its foundational status. plato.stanford.edu /entries/category-theory

warner-book.txt In a* *ny category, a morphism is an isomorphism iff it is both a monomorphism and an ext* *remal epimorphism iff it is both an extremal monomorphism and an epimorphism. A category C that has a zero object is abelian iff it has pullbacks, pushouts,* * and ev- ery monomorphism (epimorphism) is the kernel (cokernel) of a morphism. In particular: F is a class, hence {F} is a conglomerate.] A metacategory_is defined in the same way as a category except that the obj* *ects and the morphisms are allowed to be conglomerates and the requirement that the conglomerate of mo* *rphisms between two objects be a set is dropped. hopf.math.purdue.edu /WarnerG/warner-book.txt

Category:Topology Definition / Category:Topology Research Topology is concerned with the study of the so-called topological properties of figures, that is to say properties that do not change under bicontinuous one-to-one transformations (called homeomorphisms). In mathematics, topologyTopology (Greek topos = place and logos = word) is a branch of mathematics concerned with the study of topological spaces. (The term topology is additionally used for a set of open sets used to define topological spaces) www.elresearch.com /Category:Topology

Grothendieck topology Article, Grothendiecktopology Information In mathematics, a Grothendieck topology is a structuredefined on an arbitrary category C which allows thedefinition of sheaves on C, and with that the definition of general cohomology theories. Note that a Grothendieck topology is not a topology in the classical sense. This is the defining property of a sheaf, and a Grothendieck topology on C is an attempt to capturethe essence of what is needed to define sheaves on C. www.anoca.org /vi/category/grothendieck_topology.html

Fibrewise General Topology: A Brief Outlook by David Buhagiar The study of General Topology is usually concerned with the category TOP of topological spaces as objects, and continuous maps as morphisms. It would be beneficial to have a more systematic way of extending definitions and results from the category TOP to the category MAP and some hope is provided by the link between Fibrewise Topology and Topos Theory [13, 14, 16, 17]. In [2, 3], a category of maps MAP in which one does not restrain oneself with a fixed base space Y was studied. at.yorku.ca /t/a/i/c/34.htm

agmod-I-fin-web.txt To motivate this terminology we prove a criterion characterizing fibrant objects in the mod* *el category of stacks as objects satisfying a hyper-descent property with respect to the given S-topolog* *y, which is a homotopy analog of the usual descent or sheaf condition. The category obtained from T0 by passing to the quotient with respect to this equivalence re* *lation is precisely Ho(T). However, the main advantage of Segal categories is the existence of a theory of internal Hom's th* *at allows to define a reasonable notion of Segal category of morphisms between two Segal categories. hopf.math.purdue.edu /Toen-Vezzosi/agmod-I-fin-web.txt
