An asymmetric relation R is a relation that is not symmetric.
A preorder is a binary relation that is reflexive and transitive.
A relation R on a set X is transitive, if x R y and y R z imply x R z, for all elements x, y, z in X.

 Domain theory - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-10-21)
Domain theory formalizes the intuitive ideas of approximation and convergence in a very general way and has close relations to topology.
In a purely syntactic way, one can go from simple functions to functions that take other functions as their input arguments.
In addition, the domain of computation is equipped with an ordering relation, in which the "undefined result" is the least element.

It is a mechanism by which promoters of so-called "investment" or "trading" schemes enrich themselves in a geometric progression through the payments made by recruits to such schemes.
Related deceitful schemes have been described in various international jurisdictions as "chain letters," "snow balls," "chain selling," "money games," "referral selling" and "investment lotteries".
Should the pyramid scheme collapse, there is no way for the participants to recover their "investments".

As a result, unemployment has been rising slightly but at 4% is still way below that of France or Germany.
Part of the reason, they argue, is that while Swiss companies that trade internationally are often world-class, the often heavily subsidised domestic sector, immune from EU competition rules, has become much less competitive.
They also argue that Switzerland's odd position in relation to the EU - receiving all the advantages of trading in a common market with few of the disadvantages of abiding by its rules - is not sustainable.

 The ``Way-Below'' Relation
Some authors prefer the term ``relatively compact" or ``way inside", since in the poset of open sets of a topology it is natural to read $U \ll V$ as ``$U$ is relatively compact in $V$".
A compact element of a poset (or an element isolated from below) is defined to be way below itself.
So, the compactness in the poset of open sets of a topology is equivalent to the compactness in that topology.\par The article includes definitions, facts and examples 1.1-1.8 presented in [11, pp.

We show, in an intuitionistic way, that the patch construction exhibits the category of Stone locales as a coreflective full subcategory of the category of spectral locales and perfect maps.
Here a continuous map is perfect iff its associated frame homomorphism preserves the way-below relation iff its right adjoint is Scott continuous (topologically, iff it reflects compact upper sets).
The category of stably locally compact locales includes (the point-free versions of) Scott domains, SFP domains, FS domains, and Lawson compact continuous dcpos (in ascending generality), and at the same time Hausdorff objects like the unit interval and Cantor space.

umanity's unrestricted faith in relation to its cerebral abilities has already been here for a long time, in fact, for thousands of years, and the successive successes in gross matter were of excellent service to further confirm this idea.
The big mistake occurs when, motivated by these visible successes, scientists feel that they are equally capable of examining, with their intellect, restricted to matter, things that are found outside the sphere of matter.
They are in fact at the height of intellectual knowledge this however is at a very inferior step, way down below in relation to the knowledge that we could have had of the immense work of Creation, had we made full use of our spiritual capacities.

One is in relation to section 55 of the Nationality, Immigration and Asylum Act 2002, which we pointed out was almost certain to lead to inhuman and degrading treatment of asylum seekers in contravention of Article 3.
We remained of the view that problems might remain in relation to unrepresented children, and suggested the bill be amended to require the court to appoint legal representatives for unrepresented child defendants.

D], although on reflection these were anyway rather naïve attempts to capture the way in which we think of physical bodies.
With this, ASD gives a logical treatment of standard topological notions, such as a definition of compactness that is related to the universal quantifier but much simpler than the traditional one.
An object of the category can then be defined using finitary data about a basis of open subspaces and a related family of compact ones, maybe obtained from a space that is locally compact in the external sense.
