摘要
利用完全正映射与相似 同态问题的关系 ,给出了满足特殊条件具有相同算子值的两个算子 。
In this note, we give a necessary and sufficient condition of the range subspace, which is the same range of two operators that satisfy special conditions, being invariant para\|closed subspace of some operator system, by making use of the relation between completely positive map and similary*\|homomorphism problem.
