	Maschke theorem - Wikipedia, the free encyclopedia
		It is related to the Artin-Wedderburn theorem, which gives a decomposition of a finite-dimensional semisimple algebra into a finite product of algebras of matrices.
		In fact Maschke's theorem is a justification for applying the Artin-Wedderburn theorem to the group algebra.
		abstract algebra, the theorem characterises the good cases, for which the required behaviour will hold, in terms of the properties of the underlying field of scalars.

	Search Results for Artin
		Artin was at the Institute during Iwasawa's two years there and he was one of the main factors in changing the direction of Iwasawa's research to algebraic number theory.
		One was Artin 's Geometric Algebra which she read and loved, a second was a chance to attend seminars at Cornell over the summer of 1962 while her husband was there on a research visit, and the third was an inspiring discussion she had with Hanna Neumann when she visited Mount Holyoke College.
		Artin 's scientific achievements are only partially set forth in his papers and textbooks and in the drafts of his lectures, which often contain new insights.

		Closely related is the notion of ideals, certain subsets of rings which arise as kernels of homomorphisms and can serve to define factor rings.

	Artin-Wedderburn theorem Info - Encyclopedia WikiWhat.com
		In mathematics, the Artin-Wedderburn theorem is a classification theorem for simple rings.
		The theorem states that a simple ring R that is Artinian is isomorphic with the n x n matrix ring over a division ring D, for some integer n.
		It applies in particular to the case of rings that are an algebra over a field, and finite-dimensional over it (Wedderburn's original case).

	Pure Math Course Descriptions
		It is a subject of great beauty, with connections to numerous parts of mathematics, such as the prime number theorem, the fundamental theorem of algebra, the Jordan canonical form theorem for matrices, the Weierstrass approximation theorem, the evaluation of "improper" integrals, the geometry of transformations, and the harmonic functions of fluid mechanics.
		The elegant theorems that result can then be applied to yield surprising conclusions in areas such as combinatorics, geometry, coding theory, physics, and computer science.

		Theorem 2..11 (Wedderburn's Structure Theorem) The following statements for a ring R are equivalent.
		The word left is obsolete as becomes clear from Wedderburn's structure theorem.
		Implication of statement 3 from statement 2 was quite long and took the rest of the lecture.

	Artin-Wedderburn Theory

		We study semisimple modules and prove the structure theorem for semisimple algebras.

	PlanetMath: semiprimitive ring
		The Artin-Wedderburn Theorem states that any semiprimitive ring which is left or right Artinian is isomorphic to a finite direct product of matrix rings over division rings.
		A finite direct product of matrix rings over division rings can be shown to be semiprimitive and both left and right Artinian.
		Note: The 'semiprimitive' condition is sometimes also referred to as a semisimple, Jacobson semisimple, or J-semisimple.

		By Wedderburn's Theorem (Theorem 6) we may assume that $$R = \fatm_n(D)$$ for some division ring $D$ and some $n\in \fatn$.
		We will omit the proof of uniqueness for $M$ not finitely generated, but it is proved either from the Azumaya version of Krull-Schmidt or by using the Morita Theorem that we will treat in the Exercises.\qed \medskip Now let $R$ be a semisimple ring.
		\qed} This together with Theorem 12 of the last Lecture means that a ring is left semisimple iff it is right semisimple.

	MANIFOLD-10: Mathematics of the 70s
		A famous theorem of Artin-Wedderburn says that every simple ring with minimum condition is isomorphic to a complete matrix ring over a division.
		A theorem of Goldie says that every simple Noetherian ring has a ring of quotients which is a simple ring with minimum condition.
		This result can be extended to general computable metric spaces which are totally bounded, this generalization being the constructive analogue of the theorem asserting the continuity of the inverse function of a continuous injective function defined on a compact space.

	Simple ring
		According to the Artin-Wedderburn theorem, every simple ring that is left or right Artinian is a matrix ring over a division ring.
		In particular, the only simple rings that are a finite-dimensional vector space over the real number s are rings of matrices over either the real numbers, the complex number s, or the quaternion s.
		A simple ring can always be considered as a simple algebra.
