【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(M_ΓR)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.更多还原

【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 {e_iα_i}andρ-simple ringsR_i such thatR（?）End（M_iг₀D_i）M_i=〈R_iα_ie_i〉〉^ρ,and D_i=〈e_iα_iR_iα_ie_i〉^ρ.更多还原
