ρ—半单Γ。—环的结构
Structure of ρ-semisimple Γ。-Rings
【摘要】 本文首先定义了Γ一环的ρ一理想,从而引入了ρ一根;并且定义了乘法使得 End(MΓR)成为Γ一环,并得到了具有一定条件的ρ一半单Γ(?)一环的结构定理.
【Abstract】 In this paper we proved that R is a ρ-semisimple Γ0-ring if andonly if R is a direct sum of finitely many ρ-semple ideal subringof Γ0-Ring R.If R is a ρ-semisimple Γ0-ring,then there exist strongly idempetent elements {eiαi}andρ-simple ringsRi such thatR(?)End(Miг0Di)Mi=〈Riαiei〉〉ρ,and Di=〈eiαiRiαiei〉ρ.
