摘要：

The difference AB-BA of two matrices A and B is called the commutator (or Lie product). In this paper, we are concerned with inequalities for the Frobenius norm of commutators based on other products, including the Kronecker product, the Khatri-Rao product, the contracted product, and the T-product. We also study the characterization of their corresponding maximal pairs.
