@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. recent news On August 29, Hurricane Katrina hit the Gulf Coast of the United States. Damage was especially severe in Louisiana; a majority of the New Orleans area is flooded, with some parts under 20 feet of water. Our colleagues in the affected areas, particularly those at Tulane University, could use our help. If you can offer a place to stay temporarily, or need a seminar speaker or two in the next couple of weeks, let us know (email at webmaster@commalg.org ) and we'll put you in touch. Also, we'd like to collect reports of people who are ok, as well as those who could use a little help. We're thinking of you. update 1 Sept: We've heard from Tulane colleagues Christine Cumming and Brent Strunk (in Dallas), and Tai Ha and his wife (in Houston). Everyone is OK. update 12 Sept: Tulane has cancelled classes for the fall semester. More recent news from the commalg community.

ABOUT: Introduction History Related areas Subfields POINTERS: Texts Software Web links Selected topics here 13: Commutative rings and algebras Introduction Commutative rings and algebras are sets like the set of integers, allowing addition and (commutative) multiplication. Of particular interest are several classes of rings of interest in number theory, field theory, algebraic geometry, and related areas; however, other classes of rings arise, and a rich structure theory arises to analyze commutative rings in general, using the concepts of ideals, localizations, and homological algebra. A commutative ring is a set endowed with two binary operations "+" and "*" subject to familiar associative, commutative, and distributive laws. (It is usually but not universally assumed that the rings contain an identity element "1" for multiplication.) Examples include the rings of integers in algebraic number fields; here, the interest is number-theoretic: common questions concern factorization and the class group, the action of the Galois group, and the structure of the group of units. A commutative algebra is a commutative ring which contains a field (usually as a subring over which the entire ring is finitely-generated). Examples include coordinate rings of algebraic varieties, that is, quotients of polynomial rings over a field; here, the interest is geometric: how are the local rings different at singular points, and how do subvarieties intersect? In some sense the theory of commutative rings and algebras can be seen as the search for common features of these two classes of examples, and the effort to explain features of a general commutative ring as being like these two types. We can clarify these fields of inquiry by reviewing the subfields of section 13.

For now this page is largely a placeholder; more information is on the parent page for commutative algebra History Applications and related fields The computational tools described on this page are used in other areas, particularly algebraic geometry and its subfields (e.g. one can compute the envelope of a curve ). Roughly speaking we have included here the comments which are best exemplified with varieties of dimension zero (finite sets of points) and in section 14 the comments which involve more geometry than computation.
