Zusammenfassung der Ergebnisse,This chapter will be devoted to the study of two classes of rings, namely, semiperfect rings and left (resp., right) perfect rings. The notion of semiperfect rings is left-right symmetric, while left (resp., right) perfect rings are always semiperfect.

https://doi.org/10.1007/978-3-8274-2736-6wenty years later, E. Noether and E. Artin introduced the Ascending Chain Condition (.) and the Descending Chain Condition (.) as substitutes for finite dimensionality, and Artin proved the analogue of Wedderburn’s Theorem for general semisimple rings. The Wedderburn-Artin theory has since become th

Zusammenfassung und Implikationen, the radical was studied first in the context of nonassociative rings (namely, finite-dimensional Lie algebras) rather than associative rings. In the work of E. Cartan, the radical of a finite-dimensional Lie algebra . (say over ℂ) is defined to be the maximal solvable ideal of .: it is obtained as

Zusammenfassung und Implikationen,of groups. We have already explained, in the introduction to §6, how ring theory may be brought to bear on group representation theory by viewing representations as modules over group rings. From this viewpoint, many facts in the representation theory and character theory of finite groups can be ded

Zusammenfassung der Ergebnisse,tivity, so by using exactly the same conditions on rings in general, we can define (and we have defined) the notions of ., and .. However, a little careful thought will show that this is not the only way to generalize the former three classes. In fact, the defining conditions for these classes are c
