Macaulay2 version 1.6 available

[Daniel R. Grayson]

Dear Macaulay2 users,

We announce the availability of Macaulay2 version 1.6.  It includes the

following new packages:

  - PushForward, a package for for computing the push-forward functor for

    finite ring maps, by Claudiu Raicu.

  - EliminationMatrices, a package for computing resultants, by Nicolás Botbol,

    Laurent Busé, and Manuel Dubinsky.

  - EllipticIntegrals, a package for numerical computation of elliptic

    integrals and elliptic functions, by Dan Grayson.

  - Triplets, a package for computing Betti diagrams and hypercohomology tables

    associated to triplets of degree sequences, by Gunnar Floystad.

  - CompleteIntersectionResolutions, a package for analyzing the asymptotic

    structure of minimal resolutions over a complete intersection, by David

    Eisenbud.

They supplement the following packages, which were first released with version

1.5:

  - Nauty and NautyGraphs, packages for an interface to the program nauty,

    which provides efficient methods for determining whether graphs are

    isomorphic, generating all graphs with particular properties, generating

    random graphs, and more, by David Cook II.

  - NumericalAlgebraicGeometry, a package for using polynomial homotopy

    continuation to solve systems of polynomial equations and describing

    positive-dimensional complex algebraic varieties, by Anton Leykin.

  - Binomials, a package for binomial ideals with a particular focus on

    intersection decompositions and associated primes, by Thomas Kahle.

  - BIBasis, a package for constructing reduced Pommaret and Gröbner bases in a

    Boolean ring, by Mikhail Zinin.

  - CharacteristicClasses, a package for degrees of Chern classes and other

    characteristic classes of projective schemes, by Christine Jost.

  - KustinMiller, a package for unprojection and the Kustin-Miller complex

    construction, by Janko Boehm and Stavros Papadakis.  It has since been been

    published in JSAG.

  - MonomialAlgebras, a package for decomposing a monomial algebra as a module

    over a subalgebra, by David Eisenbud, Janko Boehm, and Max Nitsche.

  - MonomialMultiplierIdeals, a package for computing multiplier ideals of

    monomial ideals, by Zach Teitler.

  - QthPower, a package for computing the integral closure of type I affine

    domains, by Douglas A. Leonard.

  - RandomObjects, RandomCanonicalCurves, RandomCurves (missing documentation),

    RandomGenus14Curves, RandomPlaneCurves (missing documentation), and

    RandomSpaceCurves, packages for the construction of random points of

    unirational moduli spaces, by various subsets of Hans-Christian Graf

    v. Bothmer, Florian Geiss, and Frank-Olaf Schreyer.

  - TensorComplexes, a package for multilinear algebra for the construction of

    tensor complexes, by David Eisenbud, Daniel Erman, Gregory G. Smith, and

    Dumitru Stamate.

  - VersalDeformations, a package for calculating tangent and obstruction

    spaces as well as power series solutions for deformation problems involving

    isolated singularities and projective schemes, by Nathan Owen Ilten.  It

    has since been been published in JSAG.

for the list of changes since version 1.5.

Compiled distributions are available for most operating systems at

http://macaulay2.com/, and a few more will be produced over the forthcoming

week.

Those wishing to compile further distributions may use the tag

"release-1.6-stable-20130514" in the github repository at

https://github.com/Macaulay2/M2 or the corresponding tar file at

http://www.math.illinois.edu/Macaulay2/Downloads/SourceCode/.

Let us know if you have any difficulties.  A convenient way to report an issue,

after signing up for "github", is available for your use at

Hello,

Will the libraries for version 1.6 be posted on
http://www.math.illinois.edu/Macaulay2/Downloads/OtherSourceCode/
? Currently there is a link, but no files under "1.6"

Thank you!
Andrey

The libraries are posted, but it started to seem laborious to maintain
the convention that the libraries for 1.6 are stored in that
particular URL. So the automated downloads will succeed, never fear.

Yes, but what if I want to have a source code that will not require
any additional downloads or internet connection (for packaging in
Sage)? Is there any "official" place where I should be getting
libraries for 1.6?
