摘要：
In this paper we characterize when the product of two block Hankel operators on the vector-valued Hardy space is a Hankel operator. We also describe when a block Toeplitz and a block Hankel operator commute. These characterizations extend results in two recent papers by T. Yoshino and R.A. Martinez-Avendano respectively.
