@import "/style.css"; Welcome to commalg.org! commalg.org is a website devoted to the collection and dissemination of information relevant to the commutative algebra community. This information is collected in six areas: Conference Announcements. This is where we post information about upcoming conferences that focus, at least partially, on commutative algebra. Use this form to submit a conference announcement. Imminent conferences can be found in the right sidebar. Preprint Announcements. This is where we provide links to preprints in commutative algebra. Unfortunately, commalg.org is not a preprint server, that is, we do not store preprints here. Thankfully, the arXiv preprint server ( what? ) has a section devoted to Commutative Algebra . We encourage you to post your own preprints to the arXiv server, even if you already post them to your personal webpage ( why? ). Use this form to submit information regarding new or previously unannounced preprints. News. This is an area for general information about the commalg community not included in the sections above. Examples of news include, but are not restricted to, announcements of awards being made to commutative algebraists, photos from conferences being posted, or (other things else we haven't thought of). Use this form to submit news to be posted.

Calendar Commutative Algebra August 19, 2002 to May 16, 2003 at the Mathematical Sciences Research Institute, Berkeley, California Organized by: Luchezar Avramov, Mark Green, Craig Huneke, Karen E. Smith and Bernd Sturmfels A significant development over the last 20 years is the role that commutative algebra is taking as a tool for solving problems from a rapidly expanding list of disciplines. In oversimplified terms, the process could be described as follows: Mathematicians with various backgrounds discover ways of encoding information of interest into commutative rings and their modules, then use algebraic concepts, methods, and results to analyze that information efficiently. A famous example of such encoding is the translation of an abstract finite simiplicial complex into an ideal represented by the zeroes of square-free monomials in a set of variables corresponding to the vertices of the simplicial complex. Of course, the existing body of work in commutative algebra is not tailored to suit all new demands. This is precisely where the subject benefits most from the recent surge of external interest, as it receives an influx of novel questions, points of view, and expertise. Our year-long program will highlight these recent developments and will include the following areas: Tight closure and characteristic p methods Toric algebra and geometry Homological algebra Representation theory Singularities and intersection theory Combinatorics and Grobner bases

Commutative Algebra and Geometry March 29 - April 03, 2003 Organizers: Mark Green (IPAM, UCLA), Jurgen Herzog (Univ-Gesamthochschule-Essen), Bernd Sturmfels (UC Berkeley) Objectives We are proposing a one-week regular conference (40 participants) on commutative algebra, with an emphasis on interactions with algebraic geometry, polyhedral geometry and combinatorics. This conference would be held in the Spring of 2003 and is part of the Special Program 2002/03 on Commutative Algebra at MSRI Berkeley. It is our intention to invite younger researchers and to also include first-rate mathematicians who work not in commutative algebra proper but in nearby fields. Specifically, we shall invite several leading algebraic geometers. In selecting lectures we will place a particular emphasis on recent developments, applications and future directions. The following is a sample of topics to be discussed in this workshop: toric rings and varieties, Koszul algebras, toric K-theory, exterior algebra methods, arrangements of linear subspaces, Flag varieties and Schubert varieties, Grobner bases, sagbi bases, zero-dimensional schemes, elimination theory, Hilbert schemes, singularities, invariant theory. All of these topics are highly relevant for applications of commutative algebra, both within mathematics and outside of mathematics. To give a concrete example for the usefulness of Commutative Algebra as scientific tool, we wish to mention the recent interaction with Statistics. An introduction to this can be found in the book Giovanni Pistone, Eva Riccomagno and Henry Wynn: Algebraic Statistics: Computational Commutative Algebra in Statistics, Chapman and Hall, Boca Raton, London, 2001, ISBN: 1-58488-204-2 The proposed workshop at Banff deals with fundamental problems whose solutions will benefit practical applications such as those in "Algebraic Statistics".

SINGULAR Introduction to Commutative Algebra" Version 2.0 Registration Manual Overview ... Impressum Book: "A S INGULAR Introduction to Commutative Algebra" This book has been written to learn commutative algebra in a new style, taking into account modern developments such as algorithmic and computational aspects. As soon as a new concept is introduced, it is shown how to handle it by computer. The computations are exemplified with the computer algebra system S INGULAR , which was developed by the authors. S INGULAR is a special system for polynomial computation with many features for global as well as for local commutative algebra and algebraic geometry. The book can be used for courses, seminars and as a basis for studying research papers in commutative algebra, computer algebra and algebraic geometry. The text starts with the theory of rings and modules and standard bases with emphasis on local rings and localization. It is followed by the central concepts of commutative algebra such as integral closure, dimension theory, primary decomposition, Hilbert function, completion, flatness and homological algebra. An appendix is devoted to algebraic geometry to show how geometric problems can be understood using commutative algebra. The book includes a CD with a distribution of S INGULAR for various platforms (Unix/Linux, Windows, Macintosh) and which contains all examples and procedures explained in the text.
