To Outside World

General.

A potentially useful site is the wikipedia site. A fine history can be found at the St. Andrews site. Further general information can be found via the websites of mathematical societies and discussion forums. Also Andrei Marcus' Homepage contains a rich collection of links to mathematics on the web and in particular to personal homepages of group theoreticians.

Mathematical and other Societies.

The St Andrews 'History of Mathematics' web site by J. O'Connor and E. Robertson contains an Alphabetical List of Mathematical Societies as well as a Chronological List of Mathematical Societies. For each Society/Academy listed, there is a link to a page describing its history and at the bottom of that page you find a link to the home page of the respective Society/Academy (where it is still current).

For convenience we give direct links to the home pages of a few Societies:

• International Mathematical Union (IMU),
• European Mathematical Society (EMS),
• American Mathematical Society (AMS),
• German Mathematical Society (DMV), in particular its Fachgruppe Computeralgebra.
• London Mathematical Society (LMS).

Also see the home page of the Association for computing Machinery (ACM) and its Special Interest Group in Symbolic and Algebraic Manipulation (ACM SIGSAM).

Conferences

A general overview can be found in the AMS Conference Calendar.
The meetings at the 'Mathematisches Forschungsinstitut Oberwolfach' can be found using the links on their homepage.
A Collection of Meetings with relation to Group theory, related topics and in particular Computational Group Theory is maintained in St Andrews.

Fora

There are several adresses for discussion of mathematical questions.

In the Group Pub Forum you have a good chance to get answers to theoretical questions from group theory and related topics.
The web page http://listserv.nodak.edu/archives/nmbrthry.html has instructions on how to subscribe, send a mail, etc. to a Number Theory List.
Each of these websites also provides lots of general information.
There are also Mathematics and MathOverflow sites which are part of the Stack Exchange network of Q&A (question and answer) sites.

People from History and Today.

The St Andrews 'History of Mathematics' web site by J. O'Connor and E. Robertson collects cvs of many mathematicians from the past and of a few outstanding ones of today.
The Mathematics Genealogy Project answers the question 'Who was who's PhD thesis advisor?' far back into history.

Reviews and Preprints

MathSciNet is a comprehensive database covering the world's mathematical literature since 1940. It provides Web access to the bibliographic data and reviews of mathematical research literature contained in the Mathematical Reviews Database and fosters the navigation of mathematics literature by providing links to original articles and other original documents, when available.

Its competitor, Zentralblatt MATH is the world's most complete and longest running abstracting and reviewing service in pure and applied mathematics. The Zentralblatt MATH Database contains more than 2.0 million entries drawn from more than 2300 serials and journals and covers the period from 1868 - present by the recent integration of the Jahrbuch database (JFM). The entries are classified according to the Mathematics Subject Classification Scheme (MSC 2000).

ArXiv is an e-print service in the fields of physics, mathematics, non-linear science, computer science, and quantitative biology, operated by Cornell University. See also David Benson's Preprint Archive on Groups, Representations and Cohomology.
