AI 中文摘要
对于两个复方矩阵A、B和实数q,A与B的q-变形对易子定义为AB - qBA。我们在q≥0的情况下,给出了该q-变形对易子的Frobenius范数的若干上界,本文推导的所有不等式均推广了Böttcher-Wenzel不等式。
英文摘要
For two square complex matrices $A,B,$ and a real number $q$, the $q$-deformed commutator of $A$ and $B$ is defined as $AB-qBA$. We give some upper bounds on the Frobenius norm of the $q$-deformed commutator in the case $q\ge0$. All of the inequalities derived in this paper generalize the Böttcher-Wenzel inequality.
