Falling somewhere in a category between Einstein's theory and sand fleas -- difficult to see but undeniably there, nevertheless -- is the tropical green `` city '' of Islandia, a string of offshore islands that has almost no residents, limited access and an unlimited future.

Because there is no canonical well-ordering of all sets, a construction that relies on a well-ordering may not produce a canonical result, even if a canonical result is desired ( as is often the case in category theory ).

There are several results in category theory which invoke the axiom of choice for their proof.

On the other hand, other foundational descriptions of category theory are considerably stronger, and an identical category-theoretic statement of choice may be stronger than the standard formulation, à la class theory, mentioned above.

The most general setting in which these words have meaning is an abstract branch of mathematics called category theory.

In category theory, an automorphism is an endomorphism ( i. e. a morphism from an object to itself ) which is also an isomorphism ( in the categorical sense of the word ).

This is a very abstract definition since, in category theory, morphisms aren't necessarily functions and objects aren't necessarily sets.

His research program vastly extended the scope of the field, incorporating major elements of commutative algebra, homological algebra, sheaf theory, and category theory into its foundations.

His emphasis on the role of universal properties brought category theory into the mainstream as an important organizing principle.

During this time he had officially as students Michel Demazure ( who worked on SGA3, on group schemes ), Luc Illusie ( cotangent complex ), Michel Raynaud, Jean-Louis Verdier ( cofounder of the derived category theory ) and Pierre Deligne.

Alexander Grothendieck's work during the ` Golden Age ' period at IHÉS established several unifying themes in algebraic geometry, number theory, topology, category theory and complex analysis.

He gave lectures on category theory in the forests surrounding Hanoi while the city was being bombed, to protest against the Vietnam War ( The Life and Work of Alexander Grothendieck, American Mathematical Monthly, vol.

The choice between the two definitions usually matters only in very formal contexts, like category theory.

In category theory, n-ary functions generalise to n-ary morphisms in a multicategory.

* Cone ( category theory ), a family of morphisms resembling a geometric cone

Notable theories falling into this category include the Holonomic brain theory of Karl Pribram and David Bohm, and the Orch-OR theory formulated by Stuart Hameroff and Roger Penrose.

In applying the elemental theory to beings that function on a cosmic scale ( e. g. Yog-Sothoth ) some authors created a separate category termed aethyr.

Many significant areas of mathematics can be formalised as categories, and the use of category theory allows many intricate and subtle mathematical results in these fields to be stated, and proved, in a much simpler way than without the use of categories.

However it is important to note that the objects of a category need not be sets nor the arrows functions ; any way of formalising a mathematical concept such that it meets the basic conditions on the behaviour of objects and arrows is a valid category, and all the results of category theory will apply to it.

" An abstraction " is the product of this process – a concept that acts as a super-categorical noun for all subordinate concepts, and connects any related concepts as a group, field, or category.

At the very least, category theoretic language clarifies what exactly these related areas have in common ( in some abstract sense ).

The Norwegian expressions seldom appear in genuine folklore, and when they do, they are always used synonymous to huldrefolk or vetter, a category of earth-dwelling beings generally held to be more related to Norse dwarves than elves which is comparable to the Icelandic huldufólk ( hidden people ).

Researchers have ( semi-seriously ) performed lossy compression on text by either using a thesaurus to substitute short words for long ones, or generative text techniques, although these sometimes fall into the related category of lossy data conversion.

A related and reciprocal category of dreams that are lucid in terms of some of these four corollaries, but miss the realization that " I'm dreaming ," were also reported.

A closely related category is soramimi — songs that produce unintended meanings when translated to another language.

A related drug, Paracetamol or " acetaminophen " is often considered in the same category as NSAIDS due to its use as a non-narcotic analgesic and fever-reducing agent, but is not classified as a NSAID because it only exerts weak anti-inflammatory effects.

Equivalently, a preordered set P can be defined as a category with objects the elements of P, and each hom-set having at most one element ( one for objects which are related, zero otherwise ).

The loaning of fire related records to the military has declined since 2006, since a large number of such records now fall into the " archival records " category of military service records meaning that the records have been transferred from the military to the National Archives.

Human colonization is a narrower category than the related concept of colonialism.

Like several of the other fields that are categorized within zoology, entomology is a taxon-based category ; any form of scientific study in which there is a focus on insect related inquiries is, by definition, entomology.

The terms special edition, limited edition and variants such as deluxe edition, collector's edition and others, fall under the category of manufactured collectable and are used as a marketing incentive for various kinds of products, originally published products related to the arts, such as books, prints or recorded music and films, but now including cars, fine wine and other collectables.

Below this is a list of encrypted words which are related to the stated category.

An alternative scheme proposed that jawed-vertebrates are more closely related to lampreys than to hagfish ( i. e., that vertebrates include lampreys but exclude hagfish ), and introduces the category craniata to group vertebrates near hagfish.

LGB respondents reported higher rates of perceived discrimination than heterosexuals in every category related to discrimination, the team found.

Today, hurricane force winds are sometimes described as Beaufort scale 12 through 16, very roughly related to the respective category speeds of the Saffir – Simpson Hurricane Scale, by which actual hurricanes are measured, where Category 1 is equivalent to Beaufort 12.

It has to be borne in mind that any typological system has heuristic value as a convenience for description, and need not reflect phylogeny: each category ( term ) may include representatives of many distantly related taxa, each of which may well have close relatives that are in another category ( term ) or that are not migratory and thus fall completely outside the typology.

While the two are combined for the purposes of the International Organization for Standardization ( ISO ) category, they are not administratively related.

* Passive range of motion, a category of therapeutic exercises related to joint range of motion

The idea of monomania was developed by Esquirol as a diagnostic category in his work Des Malades Mentales ( 1839 ) and related to the idée fixe by Griesinger ( 1845 ) who viewed " every single idée fixe the expression of a deeply deranged psychic individuality and probably an indicator of an incipient form of mania ".

The artists category became artwork in 1995 and a category for related non-fiction was added in 2002.

The dances in the second category are more closely related to social ballroom dancing.
