Bug 187562 – sci-mathematics/singular-3.0.0 version bump

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description M. Edward Borasky 2007-08-03 02:21:44 UTC]

Dear Singular users,
we would like to announce the release of Singular version 3-0-3.

The current version 3-0-3 is stabilyzing release,
a result of a long beta test and the integration of a lot of small fixess
which were on our waiting list for integration. 

The provided libraries and documentation were revisited.

The source code  and binary packages for Windows, serveral Linux versions
and some other Unix systems are available
from http://www.singular.uni-kl.de

Singular 3-0-3 contains also a lot of new features: 

Licence:
- licence changed: omalloc and MP are now (also) available under GPL;
     that means that all parts of SINGULAR are licenced under
     GPL (resp. LGPL). 

Porting:
- factory, libfac, Singular updated for gcc 4.1.x 
- kernel updated for the optional use of boost. 
- Singular can now be built as a library. 

Kernel:
- new operator a:b gives an intvec of length b with constant entries a 
- new command: ( chinrem): lifting via chinese remainder theorem 
- new command: ( interpolation): ideal of points with given multiplicities 
- non-commutative kernel subsystem was rewritten in order to support
  specific algebras more efficiently. Implemented algebras at the
  moment: super-commutative algebras (in particular exterior algebras). 
- std et al.: new selection strategy for reductions ( option (length)). 
- reduce: new strategy for selection and normalization. 
- simplify slightly changed: does not omit zero polynomial unless specified. 

Libraries:
- new library: compregb.lib : comprehensive Groebner base system 
- new library: kskernel.lib : kernel of the kodaira-spencer map for irreducible plane curve singularities 
- new library: modstd.lib : Groebner base computations over the rational numbers via modular computations 
- new library: noether.lib : Noether normalization of an ideal(not nessecary homogeneous) 
- new library: atkins.lib : the elliptic curve primality test of Atkin 
- new library: aksaka.lib : primality testing after Agrawal, Saxena, Kayal 
- new library: arcpoint.lib : truncations of arcs at a singular point 
- new library: resgraph.lib : visualization of resolution data. 
- new library: realrad.lib : computation of the real radical over the rational numbers and extensions thereof 
- new library: hyperel.lib : divisors in the jacobian of hyperelliptic curves 
- new library: curvepar.lib : space curves 
- new library: sagbi.lib : subalgebras bases analogous to Groebner bases for ideals 
- new library: surfex.lib : visualizing and rotating surfaces 
- new library: cimonom.lib : determines if the toric ideal of an affine monomial curve is a complete intersection. 
- sheafcoh_lib: new experimental functions, in particular sheafCohBGG2 
- library ncall.lib merged into all_lib 
- library center.lib renamed to central.lib
- nctools_lib: new functions for super-commutative algebras (i.e. SuperCommutative, IsSCA, AltVarStart, AltVarEnd) 
- resolve.lib: blow ups revised 

- new algorithms in primdec.lib : radical et al. 
- improved version of slimgb, incorporated into groebner, strategy change in groebner 
- finvar.lib: the algorithm of secondary_char0 is now used in general in the non-modular case
- finvar.lib: new algorithm for irred_secondary_char0
- finvar.lib: new function irred_secondary_no_molien
- finvar.lib: new functions for computing minimal generating sets of invariant rings of finite groups in the non-modular case:
     invariant_algebra_reynolds for finite matrix groups and invariant_algebra_perm for permutation groups
     operation for sparse matrices improved: multiplication, prune, conversion to module 

Good luck and enjoy!

Your Singular Team

Thanks for the heads-up! Hopefully I'll get to it on the weekend.

cheers,
Markus

Thanks,
Markus
