Macaulay2 is a free computer algebra system dedicated to the qualitative investigation of systems of polynomial equations in many variables. It was developed by Daniel Grayson and Michael Stillman with NSF funding. Grayson and Stillman will continue the development of Macaulay2. They will upgrade existing algorithms, develop and publish new algorithms, and implement new algorithms. In particular, they will develop the interaction of the symbolic computations that are Macaulay2's strength with the new floating point algorithms in algebraic geometry that are now being developed by Andrew Sommese, Jan Verschelde, Anton Leykin, Frank Schreyer and others. It is anticipated that these will make a whole new class of problems accessible to experimentation and, in many cases, solution. Eisenbud will organize contacts for the extended integration with other systems and will engage other mathematicians in the development work that needs to be done. Central to the project are the continued expansion of the collaborations that have been the hallmark of Macaulay2 development. For this purpose two Macaulay2 Workgroup Meetings will be held in the course of the two-year grant. One particular research problem to be attacked is: the use of computational systems to (probabilistically) disprove, or suggest a proof of, the Jacobian Conjecture on polynomial automorphisms of affine spaces (this will require the use the new floating point algorithms). Other areas where new algorithms can make an impact include the study of numerical systems, fractions with specified types of denominators, ideal factorization, systems where the multiplication of the variables doesn't satisfy the commutative law, geometric optimization, the analysis of observations of gene expression levels over time, and bioinformatics. Macaulay2 is part of the infrastructure that supports mathematical research involving systems of polynomial equations in many variables. The study of such systems of polynomial equations is central in pure and applied mathematics and in physics, with recent new impacts in such fields as cryptography, robotics and string theory. Increasing computer power and the availability of programs like Macaulay2 are making a new level of experimentation possible. The experimental results found with Macaulay2 are helping in the formulation and development of tractable conjectures in mathematics as well as in physics. A measure of Macaulay2's impact is that at least 270 research papers have cited Macaulay2, several mathematicians have contributed code, and books and course materials are now using it. The PI's will develop the software further and will recruit developers from the research community. They will introduce graduate students and mathematicians to the use of computers in research mathematics and the requisite skills in programming and development of algorithms, through workgroups at Berkeley and through the appointments of graduate students as graduate assistants.

Macaulay 2是一个免费的计算机代数系统，致力于对多变量多项式方程组进行定性研究。它是由丹尼尔格雷森和迈克尔斯蒂尔曼与国家科学基金会的资金。Grayson和Stillman将继续开发Macaulay2。他们将升级现有算法，开发和发布新算法，并实现新算法。特别是，他们将开发符号计算的相互作用，这是Macaulay 2的力量与代数几何中的新浮点算法，这些算法现在正在由Andrew Sommese，Jan Verschelde，Anton Leykin，Frank Schreyer等人开发。预计这些将使一个全新的一类问题可以进行实验，并在许多情况下，解决方案。艾森巴德将组织与其他系统的扩展集成的联系，并将从事其他数学家的发展工作，需要做的。该项目的核心是继续扩大合作，这是Macaulay 2开发的标志。为此，在两年赠款期间将举行两次麦考利2工作组会议。一个需要解决的特殊研究问题是：使用计算系统（概率性地）反驳或建议证明仿射空间多项式自同构的雅可比猜想（这需要使用新的浮点算法）。新算法可以产生影响的其他领域包括数值系统的研究，具有指定类型的分解器的分数，理想因子分解，变量相乘不满足交换律的系统，几何优化，随时间推移对基因表达水平观察结果的分析，以及生物信息学。Macaulay2是支持涉及多变量多项式方程系统的数学研究的基础设施的一部分。对这种多项式方程组的研究是纯数学、应用数学和物理学的核心，最近在密码学、机器人学和弦理论等领域产生了新的影响。计算机能力的提高和Macaulay2等程序的可用性使实验达到了一个新的水平。Macaulay的实验结果有助于数学和物理学中易于处理的结构的形成和发展。Macaulay 2的影响力的一个衡量标准是，至少有270篇研究论文引用了Macaulay 2，一些数学家贡献了代码，书籍和课程材料现在正在使用它。PI将进一步开发该软件，并将从研究社区招募开发人员。他们将介绍研究生和数学家使用计算机在研究数学和必要的技能，在编程和开发算法，通过工作组在伯克利分校和通过研究生的任命为研究生助理。
