English
Noun
simple ring (plural simple rings)
- (algebra, ring theory) A ring that contains no nontrivial ideals (i.e., no (two-sided) ideals other than the zero ideal and the ring itself).
1956, Nathan Jacobson, Structure of Rings, American Mathematical Society, page 43:Theorem 2. A semi-simple ring satisfying the minimum condition can be decomposed in only one way as a direct sum of ideals which are simple rings.
1994, P. B. Bhattacharya, S. K. Jain, S. R. Nagpaul, Basic Abstract Algebra, 2nd edition, Cambridge University Press, page 204:A field is clearly a simple ring. Indeed, a commutative simple ring with unity must be a field (Problem 1, Section 1). An example of a noncommutative simple ring is Fn, the n × n matrix ring over a field F, n > 1.
2017, Ramji Lal, Algebra 2: Linear Algebra, Galois Theory, Representation theory, Group Extensions and Schur Multiplier, Springer, page 335:Since has no nonzero proper two-sided ideals, it follows from the above discussion that is a left simple ring. We shall see that every simple ring is isomorphic to for some , and for some division ring .
