N2 - In this paper we consider the block Toeplitz operators TPhi on the weighted Bergman spaceAα2(D, Cn) and we give a necessary and sufficient condition for the hyponormality of block Toeplitz operators with symbol in the class of functionsΦ=F+G* with matrix-valued polynomial functions F and G with degree 2.
