 Jacobson density theorem - Wikipedia, the free encyclopedia
In mathematics, the Jacobson density theorem in ring theory is an important generalization of the Artin-Wedderburn theorem.
That this is a division ring is a consequence of Schur's lemma.
In particular, when the ring is primitive then it is a dense subring of linear transformations of a vector space over a division ring.

In abstract algebra, a ring R is a prime ring if for any two elements a and b of R, if arb = 0 for all r in R, then either a = 0 or b = 0.
Prime rings can be regarded as a simultaneous generalization of both integral domains and matrix rings over fields.

In mathematics, a left primitive ideal in ring theory is the annihilator of a simple left module.

Corollary.} {For a ring $R$ the following are equivalent: \itemitem{} {\rm (a)} $R$ is simple and left artinian; \itemitem{} {\rm (b)} $R \cong \fatm_n(D)$ for some $n\in \fatn$ and some division ring $D$; \itemitem{} {\rm (c)} $R$ is simple and right artinian.
Also, deduce from this exercise that there are primitive rings that are not simple.
Prove that $R$ is semi--primitive iff there is an injective ring homomorphism $\phi:R \longrightarrow \prod_A S_\alpha$ where each $S_\alpha$ is the ring of operators $\End(V_\alpha)$ on a right vector space $V_\alpha$ over a division ring $D_\alpha$, and for each alpha the image $\pi_\alpha\phi(R)$ is dense in $S_\alpha$.

 ABSTRACT ALGEBRA ON LINE: Structure of Noncommutative Rings
The ring R is called a simple ring if (0) is a maximal ideal; it is called a prime ring if (0) is a prime ideal, and a semiprime ring if (0) is a semiprime ideal.
In a left Artinian ring, the notions of maximal ideal, primitive ideal, and prime ideal coincide.
If P is a primitive ideal of the ring R, then there exists a division ring D and a vector space V over D for which R/P is isomorphic to a subring of the ring of all linear transformations from V into V. Proposition.

The primitive ideal of $\g$ collects all the functions whose zero level hypersurfaces pass through $\Sigma$ and are tangent to the regular part $X_{\rm reg}$ of $X$ along $\Sigma \cap X_{\rm reg}$.
Hence, locally the primitive ideal plays a similar role to the second power of the maximal ideal of the local ring $\O_{\cc ^n, 0}$ in singularity theory.
The {\it primitive ideal of $\g$} relative to $\h$ is $$\int _{\h}\g:= \{f\in \g\mid \xi (f)\in \g \text{ for any } \xi \in \hder {\h}{\O}\}.$$ \end{Definition} \begin{Remark}\label{geometry}\rm This definition is a generalization of \cite{P1, P2}, and was generalized to higher order relative version in \cite{JS}.

We call the kill ring a "ring" because the functions that move the yank pointer wrap around from the end of the list to the beginning, or vice-versa.
Rotation of the kill ring is virtual; it does not change the value of `kill-ring'.
The effect is to rotate the ring so that the newly killed text is at the front.

Graham was never “nice.” In 1931, Graham’s company was only five years old and this work is a solid example of finding her own artistic voice.
