	Carfree Cities: City Topology
		The Reference Topology was developed in great detail for Carfree Cities and is available as a highly-detailed poster from Zazzle.com.
		Fewer than about 50 districts indicates either that the topology could be simplified or that the density could be reduced.
		Topologies supporting even larger populations can be imagined.

	Lower limit topology - Wikipedia, the free encyclopedia
		In mathematics, the lower limit topology or right half-open interval topology is a topology defined on the set R of real numbers; it is different from the standard topology on R and has a number of interesting properties.
		It is the topology generated by the basis of all half-open intervals [a,b), where a and b are real numbers.
		The lower limit topology is finer (has more open sets) than the standard topology on the real numbers (which is generated by the open intervals).

	limit (topology) (Site not responding. Last check: 2007-10-17)
		Limits are used in calculus (and other branches of mathematical analysis) to define derivatives and continuity.
		The concept of the "limit of a function" is further generalized to the concept of topological net, while the limit of a sequence is closely related to limit and direct limit in category theory.
		The limit of a sequence and the limit of a function are closely related.

		In topology and related areas of mathematics a net or Moore-Smith sequence is a generalization of a sequence, intended to unify the various notions of limit and generalize them to arbitrary topological spaces.
		In topology and related fields of mathematics, a discrete space is a particularly simple example of a topological space or similar structure, one in which the points are isolated from each other in a certain sense.
		In mathematics, particularly in topology, a topological space X is sober if every irreducible closed subset of X is the closure of exactly one singleton of X. An irreducible closed subset of X is defined to be a nonempty closed subset of X which is not the union of two...

	Closure (topology) - Wikipedia, the free encyclopedia
		The definition of a point of closure is closely related to the definition of a limit point.
		Thus, every limit point is a point of closure, but not every point of closure is a limit point.
		A point of closure which is not a limit point is an isolated point.

	Limit (mathematics) : Limit (topology)
		The mathematical concept of limit is used to describe the behavior of a function as its argument get "close" to some point (or attempts to get close to infinity), or the behavior of the elements of a sequence as their index approaches infinity.
		Limits are more interesting when they are unreachable; for example: if f(x) = (x³ - 1) / (x - 1) then, x cannot equal 1 (as that would result in division by zero); however, f(x) does approach some number c (as x approaches 1).
		The rest of this article presents the concept of limit in increasing generality, starting with sequences and functions of real numbers, then metric spaces, and culminating in the most general concept, limits of nets on topological spaces.

	Order topology - Encyclopedia.WorldSearch (Site not responding. Last check: 2007-10-17)
		In mathematics, the order topology is a topology that can be defined on any totally ordered set.
		It is a natural generalization of the topology of the real numbers to arbitrary totally ordered sets.
		The left order topology on X is the topology whose open sets consist of intervals of the form (a, ∞).

		Roughly speaking, a topology is a way of specifying the concept of "nearness"; an open set is "near" each of its points.
		This topology on R is strictly larger than the Euclidean topology defined above; a sequence converges to a point in this topology if and only if it converges from below in the Euclidean topology.
		It is almost universally true that all "large" algebraic objects carry a natural topology which is compatible with the algebraic operations.

	Interior (topology) - Wikipedia, the free encyclopedia
		If one considers on R the topology in which every set is open, then int([0, 1]) = [0, 1].
		If one considers on R the topology in which the only open sets are the empty set and R itself, then int([0, 1]) is the empty set.
		These examples show that the interior of a set depends upon the topology of the underlying space.

	The Limit of a Sequence
		The limit point p of the sequence s is quite different from the limit point of the set s.
		Let p be a limit point of the set R in a first countable space.
		The point p is a limit point of the set R iff p is the limit of a convergent sequence taken from R. The point p is a cluster point of the sequence R iff p is the limit of a convergent subsequence of R. Weird Example

	Cisco - Understanding Spanning-Tree Protocol Topology Changes
		Topology changes can be useful, so do not enable portfast on a port for which a link that goes up or down is a significant event for the network.
		In itself, a topology change notification is not a bad thing, but as a good network administrator, it is better to know their origin in order to be sure that they are not related to a real problem.
		However, a topology change should ideally be related to a significant event in the network like a server that goes up or down or a link that transitions.

	separable (topology) (Site not responding. Last check: 2007-10-17)
		Separable spaces are therefore topological spaces with a certain limit on their size: an uncountable discrete space isn't separable.
		For technical reasons the foundations of general topology are written without the requirement of separability, or other 'axioms of countability'.
		Separability is especially important in numerical analysis and constructive mathematics, since many theorems that can be proved for nonseparable spaces have constructive proofs only for separable spaces.

	Complete space : Completeness (topology) (Site not responding. Last check: 2007-10-17)
		In mathematical analysis, a metric space M is said to be complete if every Cauchy sequence of points in M has a limit in M. In mathematical analysis, a metric space M is said to be complete if every Cauchy sequence of points in M has a limit in M.
		This is a Cauchy sequence of rational numbers, but it doesn't converge towards any rational limit; in fact, it converges towards the irrational number √2, the square root of two.
		In topology one considers topologically complete (or completely metrizable) spaces, spaces for which there exists at least one complete metric inducing the given topology.

	In The Neighborhood
		It's customary to treat the relativistic spacetime manifold as an ordinary topological space with the same topology as a four-dimensional Euclidean manifold, denoted by R
		It follows that d(a,b) ³ 0 for all a,b. Any distance function that satisfies the conditions of a metric will induce the same (local) topology on a set of points, and this will be a topological space.
		Interestingly, it is often suggested that the usual Euclidean topology of spacetime might break down on some sufficiently small scale, such as over distances on the order of the Planck length of roughly 10

		The frame of open sets of a colimit is the limit of the frames of open sets of the spaces; in particular the Aleksandrov topology (whose open sets are the upper sets) on a colimit of preorders and the Scott topology (Proposition 3.4.9) on dcpos are found as limits (from
		As we know the underlying set of a limit of spaces, identifying the topology is reduced to a lattice-theoretic problem: it is the coarsest that makes the projections continuous.
		Limits of locales (colimits of frames) are not in general the same as the corresponding limits of spaces; they must be found using generators and relations, as below.

		This limit design model covers the full range of strictly elastic, elastic/plastic and strictly plastic designs and is based on the unified analysis model of Ben-Tal and Taylor [1].
		In this paper, we study the rich class of formulations that arise in the limit analysis and design of elastic/plastic structures in the presence of contact constraints.
		The resulting limit analysis and limit design problems are nonconvex and are difficult to solve due to complementary type of equality constraints.

	Topology (Site not responding. Last check: 2007-10-17)
		A topological space is a set with the least structure necessary to define the concepts of nearness and continuity; you have met examples in real and complex analysis and perhaps also as a metric space (a set with the least structure necessary to support the concept of distance).
		General topology is concerned with the study of topological spaces and maps among them while algebraic topology is concerned with the casting of topological problems into easier algebraic form using functors.
		For proofs in topology we usually juggle the properties of open and closed sets.

		R in the lower-limit topology is not second countable: Suppose it has a countable basis B. Then given an irrational number x, and the open set [x, z), z > x there exists a basis element B_1 such that x is in B_1 c [x,z).
		Let y be another irrational number, y different from x, then there exist B_2 in B such that y is in B_2 c [y, z) and this implies that B_1 is different from B_2, (otherwise, x = y) (*).
		The product of R in the lower limit topology with itself is not second countable.
