  Group theory - Wikipedia, the free encyclopedia
Group theory is that branch of mathematics concerned with the study of groups.
A common foundation for the theory of equations on the basis of the group of permutations was found by Lagrange (1770, 1771), and on this was built the theory of substitutions.
Groups are used throughout mathematics and the sciences, often to capture the internal symmetry of other structures, in the form of automorphism groups.

Previous to this work, groups were mainly studied concretely, in the form of permutations; some aspects of abelian group theory were known in the theory of quadratic forms.
Groups underlie many other algebraic structures such as fields and vector spaces and are also important tools for studying symmetry in all its forms.
A group that we are introduced to in elementary school is the integers under addition.

permutations; some aspects of abelian group theory were known in the theory of quadratic forms.
Group Theory allows for the properties of these systems and many others to be investigated in a more general setting, and its results are widely applicable.
A group in which this equation holds for all a and b in G, is called abelian (after the mathematican Niels Abel).

 20: Group Theory and Generalizations
Group theory can be considered the study of symmetry: the collection of symmetries of some object preserving some of its structure forms a group; in some sense all groups arise this way.
Groups acting on topological spaces are the basis of equivariant topology and homotopy theory in Algebraic Topology.
Nielsen's theorem: subgroups of free groups are free.

 The Math Forum - Math Library - Group Theory   (Site not responding. Last check: 2007-11-06)
Group Theory is a branch of algebra, but has strong connections with almost all parts of mathematics.
Group theory takes an abstract approach, dealing with many mathematical systems at once and requiring only that a mathematical system obey a few simple rules, seeking then to find properties common to all systems that obey these few rules.
A short article designed to provide an introduction to finite groups - their internal properties: all those results about group theory for which a consideration of the order of elements is a central part of the question.

 HyperText Project   (Site not responding. Last check: 2007-11-06)
The subject will concentrate on a small group of critical writings, while the labs will be used to explore further possibilities of nonĀ­linear writing and reading, and hypertext publication.
A solid understanding of several key issues in hypertext theory will be sought, while in lab work students will be able to creatively explore the issues and practices of hypertext, while also producing and publishing a substantive body of work.
The particular project is to be decided by the group in consultation with the lecturer (groups will consist of three or four students) and will combine theoretical interests and practical application.

TOOLS groups were also found to be significantly more likely to recommend the system for future meetings; to have enjoyed their participation in the discussion; and to have a higher opinion of the overall quality of the discussion than did the groups not supported with tools.
Groups were required to reach consensus on the initial requirements of the APO and to submit these requirements in a formal report at the end of the experiment.
Groups in all four conditions were to (1) individually evaluate the manuscript, (2) provide ratings and justifications for the ratings on six scales; (3) share their responses with the group, and finally (4) discuss and reach agreement on ratings.

 Group Theory & Rubik's Cube
Group theory is the study of the algebra of transformations and symmetry.

 Group Theory and Quantum Mechanics
Tinkham's book is invaluable in that it develops the parts of group theory that are extremely relevant to physics and chemistry such as the theory of representations (topics that mathematicians seem bored by) and then shows beautifully how it applies to quantum mechanics.
Group theory makes much more evident what is meant by "good quantum numbers", where degeneracies come from, and other basic issues in quantum mechanics.
Particularly clever was the discussion of the Bloch wavefunction ansatz as a consequence of the Abelian symmetry group of a periodic crystal lattice.

 List of online PL theory texts   (Site not responding. Last check: 2007-11-06)
I have been gathering a small but growing list of online programming language theory reference texts at: http://www.cs.uu.nl/people/franka/ref.html These are mostly links to books that have gone out of print, and/or whose authors have been generous enough to make their work freely available.
This list is intended not only as a service to PL researchers, but also to interested members of other communities, particularly programmers without a formal research background whose interest in theoretical topics has been stimulated by (for example) exposure to modern programming languages such as Haskell, ML, Scheme and Mercury.
Therefore, this list is focused on the central topics of PL theory and semantics, and aimed at a broad, beginning graduate-level audience with the inclination and drive to self-start their own studies.

Treebanks and Linguistic Theories 2002 20th and 21st September 2002, Sozopol, Bulgaria Workshop motivation and aims Treebanks are a language resource that provides annotations of natural languages at various levels of structure: at the word level, the phrase level, the sentence level, and sometimes also at the level of function-argument structure.
Therefore the development of treebanks and formal linguistic theories need to be more tightly connected in order to ensure the necessary information flow between them.
