摘要:

对于$C^*$ -代数$A_1, A_2$,给出了从$(I_1,I_2)\to ker(q_{I_1}\otimes q_{I_2})$到$Id^{\prime}(A_1\otimes_{\mathrm{min}} A_2) is a homeomorphism onto its image which is dense in the range. Here, for a $ C^* $-algebra $ A $, the space of all proper closed two sided ideals endowed with an adequate topology is denoted $ Id^{ \prime }(A)$ and $ q_I $ is the quotient map of $ A $ onto $ A/I $. New proofs of the equivalence of the property (F) of Tomiyama for $ A_1 \otimes_{\mathrm{min}} A_2$的映射.

英文摘要:

For $C^*$-algebras $A_1, A_2$ the map $(I_1,I_2)\to ker(q_{I_1}\otimes q_{I_2})$ from $Id^{\prime}(A_1)\times Id^{\prime}(A_2)$ into $Id^{\prime}(A_1\otimes_{\mathrm{min}} A_2) is a homeomorphism onto its image which is dense in the range. Here, for a $C^*$-algebra $A$, the space of all proper closed two sided ideals endowed with an adequate topology is denoted $Id^{\prime}(A)$ and $q_I$ is the quotient map of $A$ onto $A/I$. New proofs of the equivalence of the property (F) of Tomiyama for $A_1\otimes_{\mathrm{min}} A_2$ with certain other properties are presented.
