31WHAT IS SINGULAR?
32=================
33Singular is a Computer Algebra system for polynomial computations with
34emphasize on the special needs of commutative algebra, algebraic
35geometry, and singularity theory. The main features of Singular are:
36
37 * Computations in very general rings (polynomial rings, localizations
38   of rings at a prime ideal, tensor products of rings) over many
39   ground fields (rational numbers, mod p numbers, Galois fields,
40   transcendental/algebraic extensions) and monomial orderings (all
41   standard monomial orderings, including matrix orderings)
42
43 * Very fast standard (resp. Groebner) bases computations
44
45 * Polynomial factorization, resultant, and gcd computations
46
47 * Large variety of implemented related algorithms: FGLM,
48   Hilbert-driven and factorizing Buchberger, minimal resolutions,
49   primary decomposition, ring normalization, usual ideal theoretic
50   operations; standard combinatorial algorithms.
51
52 * Efficient and flexible communication links based on the MP
53   protocol and library
54
55 * Easy-to-use, command-driven user-interface; intuitive, C-like
56   programming language
57
58 * Extensive libraries of procedures, written in Singular's
59   programming language
60
61 * Detailed on-line documentation in info and html format.
62
63 * Available for most hard-and software platforms, including most Unix
64   variants, MS-DOS, Windows 95, Windows NT, and MacOS.
65
66WHAT IS NEW IN SINGULAR VERSION 1.2?
67====================================
68Here are the highlights:
69 
70 * Commands `groebner' and `res':
71   Considerably faster Groebner (resp. standard) bases and resolution
72   computations due to improved internal implementation techniques and due to
73   heuristically chosen algorithms:
74    Groebner bases: Hilbert-driven and FGLM-based standard bases computations
75    Resolutions   : Standard-bases, Schreyer's, and  La Scala methods
76                   
77 * New Singular libraries:
78   primdec.lib  Primary decomposition based on
79                Gianni/Traeger/Zacharias and on Shimoyama/Yokoyama
80   normal.lib   Ring normalization
81   hnoether.lib Hamburger-Noether development
82   finvar.lib   Invariant rings
83   classify.lib Classification of singularities
84   deform.lib   Miniversal deformations
85   latex.lib    Typesetting Singular objects in latex
86
87 * New library format and tools to debug libraries.
88
89 * More complete and better organized documentation in various formats
90   (info, html, ps).
91
92 * Countless minor improvements (e.g., command-line arguments,
93   easier installation,  library handling, various new commands and
94   implemented algorithms).
