This distribution contains the following subdirectories 'share/Singular' -- contains Singular library files and compute tables 'info' -- contains Singular's info help file and the file 'COPYING' -- for licence and copying information information Singular.exe -- Singular executable program Installing the Singular executable program ========================================== After you have unpacked the file Singular.zip (using the command 'pkunzip -d singular' -- you can obtain the program pkunzip from The place where you obtained this ditribution), you can run Singular by (i) if you run MS-DOS: 1.) cd to the directory cotaining the File Singular.exe 2.) type Singular (ii) if you run Windows: 1.) double-click on the Singular.exe icon IMPORTANT: For the help system to work, you furthermore must have the 'info' program installed on your system, or have it reside in the same directory as the Singular executable. You can obtain the 'info' program from the same place from where you obtained this distribution. We furthermore ask you to register as a Singular user so that we can notify you about updates and news. Please do so by sending an email to singular@mathematik.uni-kl.de with the subject line "register". Overview of Singular ==================== Singular is a special-purpose computer algebra system for commutative algebra, algebraic geometry and singularity theory. The main features of Singular are: * Computations in very general rings (polynomial rings, localizations of rings at a prime ideal, tensor products of rings) over many ground fields (rational numbers, mod p numbers, Galois fields, transcendental/algebraic extensions) and monomial orderings (all standard monomial orderings, including matrix orderings) * Very fast standard (resp. Groebner) bases computations * Polynomial factorization, resultant, and gcd computations * Large variety of implemented related algorithm: FGLM, Hilbert-driven, Factorizing Buchberger; Minimal resolutions, Primary decomposition; Usual ideal theoretic operations; standard combinatorial algorithms. * Efficient and flexible communication links based on the MP protocol and library * Easy-to-use, command-driven user-interface * Intuitive, C-like programming language * Extensive libraries of procedures, written in Singular's programming language * Written in C/C++. Available as binary program for common hard- and software platforms (including most Un*x variants, MS-DOG, MacOS) Acknowledgments ================ Singular 1.0 is linked with the following libraries: gmp -- The Gnu Multiple precision library (v: 2.0.2) distribution (C) Free Software Foundation factory -- The factory library (v: 1.2c) for polynomial factorization (C) Greuel/Stobbe U of Kaiserslautern libfac -- The libfac library (v: 0.2.1) for characteristic set computations (C) Mesollen U of Saarbruecken We would like to thank all authors of these who contributed these libraries. Distribution of Singular ======================== The newest version of Singular is always available by anonymous ftp from www.mathematik.uni-kl.de:/pub/Math/Singular Binary versions of Singular for common hard- and software platforms are contained in the files bin/Singular-1.0..gz where is, for example, 'linux', 'SunOS', etc. In general, Singular is only available as binary program. For exceptions, you may contact us at singular@mathematik.uni-kl.de Architecture - independent files (such as libraries written in the Singular programming language, and the Singular documentation) are distributed as Singular-1.0-share.tar.gz. See the file README.share for more information. Documentation to Singular is distributed as: Singular-1.0.dvi.gz - Reference manual in dvi format Tutorial.dvi.gz - Singular tutorial in dvi format Singular-1.0.ps.gz - Reference manual in postscript format Tutorial.dvi.gz - Singular tutorial in postscript format singular.hlp.gz - Reference manual in Info format Singular-1.0.html.tar.gz - Reference manual in html format The GMP library and the readline library are available at ftp.gnu.ai.mit.edu or its mirrors. The MP library library is avialbale from mcs.kent.edu:/pub/MP/ For further information on MP, see also http://symbolicnet.mcs.kent.edu/areas/protocols/mp.html The factory and libfac library are available from www.mathematik.uni-kl.de:/pub/Math/ More information about Singular: Comments, Questions, Bug Reports ================================================================= More and up-to-date information about Singular is always available from http://www.mathematik.uni-kl.de/~zca/Singular We very much welcome any comments, questions, and bug reports.
