  Abstract Objects (Stanford Encyclopedia of Philosophy)
Abstract objects are defined as those that lack certain features possessed by paradigmatic concrete things.
But it is unclear what it means to call an object mental or mind-dependent; and to the extent that the notion is intelligible, it is quite unclear whether abstract objects in general satisfy the condition.
The only reason to resist this natural description would appear to be the thought that since chess is clearly an abstract object (it's not a physical object, after all!), and since abstract objects do not exist in spacetime (by definition!), chess must resemble the cosine function in its relation to space and time.

  NationMaster - Encyclopedia: Category:Abstraction
To say that a physical object is concrete is to say, approximately, that it is a particular individual that is located at a particular place and time.
Abstract things are sometimes defined as those things that do not exist in reality or exist only as sensory experience, like red.
English language and many other languages wherein abstract objects are referred to using the same sorts of nouns that signify concrete objects.

 The Theory of Abstract Objects
The theory of abstract objects is a metaphysical theory.
Abstract objects are the objects that are presupposed by our scientific conceptual framework.
Though the theory of abstract objects has been presented in books and articles, there is one unpublished source in which all the theorems of the theory are compiled in one place.

 Steps towards a logic of natural objects
The natural objects that I propose to consider are broadly those physical objects which are studied and referred to by science and by a common sense view, informed by science, of the world.
A pair of objects is not, usually, a single object (although in special cases one will consider certain pairs as a unit; for example a married couple is an object in legal considerations).
The principle of the indescribability of objects provides a contrast between natural objects and abstract objects: in set theory, the exact specification and construction of objects using Comprehension and the other constructive axioms is essential.

 Guide to Reality: Making Abstract Truths Intelligible
The problem with abstract objects is that their existence seems required to provide truthmakers for our propositions about them.
In modern discussions, abstract objects are causally inert by definition.
Unactualized possibilities may be considered “abstract” in that they are non-concrete yet real, and abstract seems as good a term as any for this mode of being (see note on terminology at end of post).

 Rule principles [was: An abstract rule model]
The state of an object at a given instant in time is the condition of the object that determines the set of all sequences of actions in which the object can take part.
The condition of an object is determined by its predicates and the objects in the roles of these predicates.
The constraint is expressed as a set of events having been raised or not raised, or the objects involved or their environment being in a specified state.

 UniOS - Object Abstract Model
Objects that have only events (code that works when it sees an event from the watcher object) can also be loaded at startup also.
Objects (including hardware abstracts) pass all information through the watcher object which can be used for diagnostic purposes, event driven scripting/programming, or even AI intervention/interaction modules.
The object would contain the architecture and abstracts it was compiled for, and if they do not match up, would re-compile to fit the machine.

 Ephilosopher :: Metaphysics and Epistemology :: The Ontology of Abstract Objects:   (Site not responding. Last check: 2007-10-26)
Remember, although all abstract objects are immaterial, it doesn’t mean all immaterial objects are abstract.
If you simply mean that non-abstract things instantiate abstract properties then that's very different to saying that the things which instantiate those properties are themselves abstract in an ontological sense.
I never thought I would be arguing over what an abstract object is. Nevertheless, I never said that because something does not exist that it is an abstract object, although it may be.

 Abstract -- Intelligent Caching for WWW Objects   (Site not responding. Last check: 2007-10-26)
Objects are removed from the short-term cache by the cache manager.
Objects are ranked by a metric which is based on when the object was last accessed, how frequently it has been accessed, and its size.
When the cache manager places an object into the long-term cache, the object is registered with the cache daemon at the remote site.

 Ed Brandon - Propositions and other Abstract Objects PH3903
For a lively and sceptical discussion of abstract objects, see Rosen in the SEP 'Abstract Objects'.
Loux usually takes universals and propositions to be abstract and takes this to mean that they are not in space-time and not in causal relations with things that are in space-time.
Another kind of thought is of the abstract as the opposite of the concrete where this does involve being in space-time and in causal connection with other things.

 The Metaphysics Research Lab
Whereas physics is the attempt to discover the laws that govern fundamental concrete objects, metaphysics is the attempt to discover the laws that systematize the fundamental abstract objects presupposed by physical science, such as natural numbers, real numbers, functions, sets and properties, physically possible objects and events, to name just a few.
The goal of metaphysics, therefore, is to develop a formal ontology, i.e., a formally precise systematization of these abstract objects.
Such a theory will be compatible with the world view of natural science if the abstract objects postulated by the theory are conceived as patterns of the natural world.

Pelton's objects tend to be floating up in the sky, as if they were heavenly revelations or visions.
Bisttram's objects tend to have at least one side or axis parallel to the sides of the canvas, giving his works a strongly rectilinear look.
Bisttram also uses transparency effects: one object will be seen "through" another object, with colors of the region modified to give the effect of seeing it through a different colored region.

 Abstract of ‘Symmetry, Structure and the Constitution of Objects’   (Site not responding. Last check: 2007-10-26)
Abstract of 'Symmetry, Structure and the Constitution of Objects'
In this paper I focus on the impact on structuralism of the quantum treatment of objects in terms of symmetry groups and, in particular, on the question as to how we might eliminate, or better, reconceptualise such objects in structural terms.
With regard to the former, both Cassirer and Eddington not only explicitly and famously tied their structuralism to the development of group theory but also drew on the quantum treatment in order to further their structuralist aims and here I sketch the relevant history with an eye on what lessons might be drawn.

 Doxazo Theos » Blog Archive » The Conceptualist Argument
Usually contrasted with concrete objects, abstract entities are things like numbers, sets (and other mathematical entities), propositions, properties (and universals), values, relations, laws, theories, etc. What all of these entities seem to have in common is the curious possession of positive ontic status without spatiotemporal extension.
With Platonism, conceptualism affirms the necessary existence of abstract objects but maintains their existence is conceptual in nature; that is, they exist not inexplicably a se but as concepts to be had by minds.
But if abstract objects exist and are mental concepts, but are not mental concepts of humans, then they must conceptually reside within another kind of mind—a mind that has the capacity to host such (metaphysically necessary) infinitude.

 notes on: The Theory of Abstract Objects
Metaphysics can be conducted as an entirely abstract theoretical study of certain possible structures for the concrete universe or parts of it, in which case it is, like mathematics, a branch of applied logic.
In Factasia, logic, including abstract ontology, and the mathematics necessary for science, are pre-requisite to metaphysics, not a part of it.
To the extent that such entities are required for logic or mathematics then they are considered in Factasia to be a part of logic or mathematics, and for these purposes set theory suffices (though other alternatives may be equally acceptable).

 Mock Objects
I wonder if this is a defensive reaction because the authors of the examples don’t want to have to justify making you fundamentally alter your coding habits and re-write all of your existing code just so that you can use their pet objects.
Mock objects help guide object-oriented programming by concentrating on what objects do, no what they are.
Routinely test-driving code with mock objects leads to premature object composition, hard-to-read and fragile code, and lost time.

A brief tupennorth on this debate: abstract objects are useful whether they're real or not; subjectIdentity elements are useful either way; beware technical solutions to non-technical problems.
For example, it's hard to think of any work on Beethoven's Fifth Symphony to which it would make any difference whether the abstract object 'Beethoven's Fifth Symphony' was real or whether it was a convenient conventional fiction to facilitate discussion and research.
From a Platonist point of view all abstract objects (Forms) are necessarily changeless and eternal.

 MULTIUSER UIMS
It is possible to use this separation in a multiuser UIMS to provide high-level abstractions for supporting sharing of both semantic values and their screen representations, as illustrated by the work on Rendezvous [Pat90] [Pat91].
An abstract object is shared among a group of users by creating a view object for each of these users and defining constraints that keep the abstract object consistent with its view objects.
All abstract objects would be stored in a single abstract process while the view objects created for different users would be kept in different view processes.
