Topic: Adjunction space

	Adjunction space - Wikipedia, the free encyclopedia
		In mathematics, an adjunction space is a common construction in topology where one topological space is attached or "glued" onto another.
		A common example of an adjunction space is given when Y is a closed n-ball (or cell) and A is the boundary of the ball, the (n−1)-sphere.
		Adjunction spaces are also used to define connected sums of manifolds.

		Remark 2 The adjunction space construction is a special case of the pushout in the category of topological spaces.
		This is version 5 of adjunction space, born on 2003-02-07, modified 2006-02-14.
		Perhaps it could be mentioned in the article, that the adjunction space is pushout in the category of topological spaces.

		A \emph{relational space} is defined as a topological space with a binary relation on the points, and a \emph{modal frame} is defined as a frame with two operations $\Box$ and $\Diamond$ satisfying various axioms.
		This papers generalises and adapts the theory of sheaves on a topological space to sheaves on a relational space: a topological space with a binary relation.
		Relational bundles on a relational space are defined as continuous, relation-preserving functions into the space, and the relational sections of a relational bundle are defined as relation-preserving partial sections.

	Quotient space - Wikipedia, the free encyclopedia
		In topology and related areas of mathematics, a quotient space (also called an identification space) is, intuitively speaking, the result of identifying or "gluing together" certain points of a given space.
		The quotient space X/~ is then homeomorphic to Y (with its quotient topology) via the homeomorphism which sends the equivalence class of x to f(x).
		The topological dimension of a quotient space can be more (as well as less) than the dimension of the original space; space-filling curves provide such examples.

	Philosophy of Real Mathematics: Klein 2-geometry II
		One would think that just as there is an adjunction between sets and groups which sends groups to their underlying sets, and sets to the free group with elements as generators, there is a 2-adjunction between categories and 2-groups.
		Real semisimple symmetric spaces are often characterised by a pair of commuting involutions of a reductive group and many of their properties are studied in this setting—in this case double cosets are of importance for representation theory of p-adic symmetric K-varieties (Helmink and Brion, 2000).
		The total space of this principal bundle is the space of objects in E(2)//O(2), and O(2) acts on this, and the quotient is the plane.

	Canonical, Lexical, and Value Spaces from Matthew Fuchs on 2002-07-10 (www-xml-schema-comments@w3.org from July to ...
		The manager s summary of what follows is that this would link lexical forms to the value space through the canonical space.
		The value here is that we wouldn t have needed to claim that 2.0 and 2.00000 are the same in the value space as only 2.0 is a canonical form, only 2.0 is in the value space and (from this perspective) 2.00000 is just another lexical form for 2.0.
		While this may only apply to the numeric types, I think it may still be worth stating, as it better separates the value space from issues arriving from the lexical forms.

	\bf The Duality Between Aglebraic Posets and Bialgebraic Frames: A Lattice Theoretic Perspective
		This adjunction restricts to several Stone-type dualities which are well-known and of considerable interest to computer scientists.
		Second, in Section 4, we restrict the primary adjunction and use mostly lattice- theoretic techniques to obtain the important Stone-type duality between algebraic posets and bialgebraic frames.
		The existence of function spaces is a highly desirable feature since, among other things, it allows the possibility of modelling recursion.

		And because they are not in space, they can be joined together as though into one, even though their bodies cannot be so joined at the same time.
		But because woman comes from man, and this conjunction is a kind of reunion, reason can see that it is not an amalgamation into one but an adjunction, nearer and closer according to the love, and to the point of contact in those who are in a state of truly conjugial love.
		This adjunction may be called a spiritual dwelling together, which occurs in the case of married partners who love each other tenderly, however separated they may be in body.

		To be specific, the modeling formulation is worked out in an incrementally modular abstraction hierarchy with emphasis on the two levels of the hierarchy appropriate for conceptual modeling: the adjunction space level and the cellular structured space level.
		Examples are shown to demonstrate the usefulness of the presented model as well as an implementation of a flower structure case.

		This definition is valid only when the formal dimension of the moduli space of solutions is zero.
		When the formal dimension is positive, one possibility to define an invariant is to use some cohomology classes to evaluate the fundamental class of the moduli space.
		However if you use this method, then the invariant is equal to be zero for all the known examples of X satisfying b_1(X)=0 and b^+_2(X) >1.

		Given a surjective map f : X → Y from a topological space X to a set Y we can define the quotient topology on Y as the finest topology for which f is continuous.
		In general, a surjective, continuous map f : X → Y is said to be a quotient map if Y has the quotient topology determined by f.

		Mathematically, one nice example of an adjunction involves a vector space x and its dual vector space x*.
		Now, as I said, an example of an adjunction is a vector space x and its dual x*.
		Well, the vector space x tensored with x* is just the vector space of linear transformations of x, so that's our monad in this case.

		In fact if SX is the simplicial sing* ular complex of a space, with its skeletal filtration, then the crossed complex (SX) can be considered as a slig htly non commutative version of the singular chains of a space*.
		The properties of this simplicial classifying space are developed in [27], and * *in particular an analogue of 1.1.7 is proved.
		The group of operators here is the fundamental group of the space X. Whitehead in [83] gave an interesting relation between his free cros* *sed complexes (he called them `homotopy systems') and such chain complexes.

	Re: Adjunction Spaces
		The main problem I'm having is that q(Y) is a >> subspace of a quotient space.
		A map p is a quotient map if and only if (p^-1(U) is open if and only if U is open.) There exist quotient maps that are neither open nor closed.
		It's pretty easy to come up with an adjunction space where the quotient map is not open.

		Geometrically, we want Vect to be related not to spaces, but to "linear structures" on spaces, in the sense that a manifold atlas genuinely describes a differentiable structure.
