Ahmed and A
We obtain some results on A-m-isometric operators. The paper consists of two parts. At first, we consider the products of A-m-isometries. It will be proved that the iterates of an A-m-isometry are all of this type. We discuss when an A-m-isometry becomes an A-isometry. Also, we consider the products of A-m-isometries for different values of m. In the second part, we are going to investigate the supercyclicity of these operators and prove that they are never supercyclic.
