Isometric NN-Jordan weighted shift operators

A bounded linear operator T on a Hilbert space is an isometric N -Jordan operator if it can be written as A + Q, where A is an isometry and Q is a nilpotent of order N such that AQ = QA. In this paper, we will show that the only isometric N -Jordan weighted shift operators are isometries. This answers a question recently raised.
