WebA ring R is called semiabelian by Weixing Chen if every idempotent e of R is either left semicentral or right semicentral, where an idempotent e of R with complementary idempotent f = 1 − e is called left semicentral if f R e = 0 and right semicentral if e R f = 0.

For an Artinian ring semiprimitive implies semisimple.

WebFeb 9, 2024 · It can be shown that there are rings which are left perfect, but not right perfect. However being semiperfect is left-right symmetric property. Some examples of … WebSemiperfect rings are rings which possess two properties of artinian rings that are crucial for the Krull{Schmidt theory: a ring Ris semiperfect (cf. [9, Ch. 8]) if (a) R=J(R) is … WebSep 21, 2016 · The structure of an Abelian ring R is completely determined in relation with the local property when X ( R) is a union of 2; 3; 4; and 5 orbits under the left regular action on X ( R) by G ( R ): For a semiperfect ring R which is not local, it is shown that if G ( R) is a cyclic group with 2 ∈ G ( R ); then R is finite. crystals newcastle upon tyne
