研究了范数函数诱导的相干测度。它表明,不能诱导的一致性措施由一个单一的相似不变范数。作为结果,人们可以推断出已知的事实,Schatten $p$-规范不诱导相干措施。对于$(p,q)\in [1,\infty]\times [1,\infty]$,列为$A_1,\dots,A_n$的矩阵的$\ell_{q,p}$-范数定义为向量$(\ell_p(A_1),\dots,\ell_p(A_n))$的$\ell_q$-范数。证明了$\ell_{q,p}$-范数诱导相干测度当且仅当$q = 1$且$p \in [1,2]$.这个结果产生了一类新的相干测度,并解释了为什么对应于$\ell_{p,p}$-范数的$\ell_p$-范数诱导出相干测度当且仅当$p = 1$。
Coherence measures induced by norm functions are studied. It is shown that a coherence measure cannot be induced by a unitary similarity invariant norm. As a consequence, one can deduce the known fact that the Schatten $p$-norms do not induce coherence measures. For $(p,q) \in [1,\infty]\times [1,\infty]$, the $\ell_{q,p}$-norm of a matrix with columns $A_1, \dots, A_n$ is defined as the $\ell_q$-norm of the vector $(\ell_p(A_1), \dots, \ell_p(A_n))$. It is shown that the $\ell_{q,p}$-norm induces a coherence measure if and only if $q = 1$ and $p \in [1,2]$. This result gives rise to a new class of coherence measures, and explains why the $\ell_p$-norm, corresponding to the $\ell_{p,p}$-norm, induces a coherence measure if and only if $p = 1$.
