摘要
本文用双中心子刻画了ＪＣ代数的乘子代数，并且研究了复Ｃ*－代数的自伴部分的乘子代数生成的Ｃ*－代数与原Ｃ*－代数的乘子代数之间的关系，最后研究了ＪＢ代数的扩张．
In this paper, we characterize the multiplier algebras of JC-algebras by double centralizers, and study the relationship between multiplier algebra M(A) of complex C* -algebra A and C*-algebra C* (M(Asa)) generated by the multiplier algebra of JC-algebra Asa, the self-adjoint part of A, Finally, we study the extension of JB-algebras.
