	Ring (mathematics) - Wikipedia, the free encyclopedia
		A ring is a generalization of the integers, which itself is an example of a ring.
		Rings that also satisfy commutativity for multiplication (such as the ring of integers) are called commutative rings.
		For n>2, this matrix ring is an example of a noncommutative ring (unless R is the trivial ring).

		A ring is a generalization of the integers, which are one example of a ring.
		Although ring addition is commutative, such that a+b = b+a, ring multiplication is not required to be commutatitve — a·b need not equal b·a.
		For example $M_n(K)$ , the ring of $n\times n$ matrices over a field K, is a non-commutative ring.

		In this context, nonassociative means that multiplication is not required to be associative, but associative multiplication is permitted.
		Thus rings,which we'll call associative rings for clarity, are a special case of nonassociative rings.
		The original example of a ring with a nonassociative multiplication was constructed by Graves in 1843.

		Lie algebras and Jordan algebras are two famous examples of non-associative algebras that are not associative.

		Alternatively, a non-associative ring is just a non-associative algebra over the integers.

	Description of my past research (Site not responding. Last check: 2007-10-13)
		Applying an old idea of Hochster we see that this ring is Cohen-Macaulay when the complex is shellable, and I show that its defining ideal is generated by quadrics when the complex is also a subcomplex of the boundary complex of a convex cubical polytope.
		This conjecture says that the h-vector of a polynomial ring in n variables modulo an ideal which has an n-element homogeneous system of parameters of degree two, is the f-vector of a simplicial complex.
		It is known that the entries of the toric h-vector have this property, and I show that the same holds for the "triangulation h-vector" which arises from the Hilbert series of the Stanley ring of a cubical complex.

	17: Nonassociative rings and algebras
		Here are a few notes on nonassociative rings; associative rings are treated in a separate section.
		There is a long FAQ on sets with products (rings), a particular emphasis of which is the study of division rings over the reals, including the nonassociative ones.
		Here the general theory is much weaker, but special cases of such rings are of key importance: Lie algebras in particular, as well as Jordan algebras and other types.

		The only simple nonassociative alternative algebra is the 8-dimensional Cayley algebra (octonion algebra) which can be obtained from the real numbers by the doubling process which gives the complex numbers, the quaternions, and then the octonions.
		Matrices with entries in an associative algebra have been studied intensively by ring theorists, but matrices with entries in a nonassociative algebra have received little attention.
		This talk will describe how the most important examples of exceptional nonassociative algebras can be described in terms of matrices over the octonions, and will then describe a research program which leads to important examples of finite-dimensional nonassociative algebras which seem to have been completely ignored.

		This book on modern module and non-commutative ring theory starts at the foundations of the subject and progresses rapidly through the basic concepts to help the reader reach current research frontiers.
		The first half of the book is concerned with free, projective, and injective modules, tensor algebras, simple modules and primitive rings, the Jacobson radical, and subdirect products.
		Later in the book, more advanced topics, such as hereditary rings, categories and functors, flat modules, and purity are introduced.
