摘要：

<正> In this paper, we study the Hankel operators belonging to E which denotes all ofthe essential Toeplitz operators, and show that the class of symbols of these Hankel operators isa Douglas algebra. Meanwhile, using the concept of essential commutant and some knowledge ofthe theory of function algebras, we solve a problem raised by Josè Barria and P. R. Halmos in [1]
