Rodgers, Manager, System Development, Mathematical Reviews e-MATH--Services for Mathematicians The American Mathematical Society, with funding from the National Science Foundation (NSF), provides a number of services to the mathematical community through its e-MATH system. Access is currently available to anyone with VT100 terminal emulation on the Internet by typing "telnet e-math.ams.org" or "telnet 130.44.1.100". Both the login name and the password are currently "e-math" (lower case). Among the services provided are the Combined Membership List of the American Mathematical Society, the Mathematical Association of America, and the Society for Industrial and Applied Mathematics; a library of public-domain software related to TeX, AMS-TeX, and AMS-Fonts; an employment information service, including all job listings which appear in the AMS publication "Employment Information in the Mathematical Sciences", plus the capability that job-hunters may post a brief curriculum vita which will be distributed to the employers with job listings; access via Gopher to a number of other services on the Internet, including preprint and directory services; listings of future AMS meetings; access to an author-lookup service based on the files of Mathematical Reviews; an electronic version of the Mathematics Classification Scheme; an electronic version of The Bulletin of the American Mathematical Society; a WAIS database containing items from the AMS Catalogue. SGML and Mathematics--A DTD for mathematics fragments A subcommittee of the American Association of Publishers (AAP) convened by W. B. Woolf (AMS) is at work on the development of a DTD (Document Type Definition) for mathematics within SGML (Standard Generalized Markup Language). It is hoped to find a DTD which synthesizes the best features of an existing draft standard from AAP and an existing International Standards Organization standard (ISO 9573 TR 1988-1). A series of meetings including representatives of Euromath, Elsevier, ISO, CERN, Springer-Verlag, AMS, and others has culminated in the creation of a small technical working committee which hopes to have a revised draft available for broad distribution late this winter. People interested in the technical issues involved can subscribe to the discussion list SGML-MATH by sending the message "subscribe sgml-math your_name" to "listserv@e-math.ams.org". Computer Algebra Netherlands (CAN) Computer algebra (CA), or symbolic computation, is concerned with software and algorithms that enable computations with symbols on a computer, hence not only with "floating point" numbers, as is the case with numerical software. Computer algebra systems, like Maple and Mathematica, are for instance capable of solving polynomial equations, of differentiating and integrating functions, and of generating Taylor expansions. This is all done in a very user friendly way. Quite often, numerical and graphical features are added. Also, a high level programming language, tailored to mathematical use, can be part of such a system. Computer Algebra Netherlands (CAN) has as its goal the stimulation and coordination of the use of computer algebra. It is an independent non-profit organization, which started with funds from the Dutch government. A long term aim is to become self-supporting. The activities of CAN include: Giving access to CA via accounts on dedicated powerful computing facilities. All kinds of CA software can be tried out and large computations can be made. All well known systems are available, but also special purpose software. An information server for computer algebra is in development, which contains information about various CA systems. The first version is running now under GOPHER. An ftp-archive is maintained by CAN with all kinds of public domain CA software (connect with name anonymous to canb.can.nl or 192.16.184.250). Also, the netlibs of REDUCE and Maple are to be found at the CAN machines. A newsletter is published regularly with information about computer algebra, seminars and conferences, new versions of systems, book reviews, etc. Courses and training material for various computer algebra systems on an introductory and advanced level are offered regularly. Scientific seminars are organized, such as SCAFI, on applications of computer algebra in industry. Distribution of software: AXIOM, DERIVE, Maple and Mathematica are available at CAN. Also various related products like special packages, books and manuals. User support at a scientific level for CA-systems and interfaces to other programmes is offered. Consultancy can be offered for projects where CA is involved. The scientific background of CAN ensures a high quality. Anybody interested in CAN or its activities can contact it at the e-mail address can@can.nl.
