ABSTRACT
An operator is said to be (m, C)-isometric if there exists a conjugation C such that
for some positive integer m. In this paper, we study (m, C)-isometric Toeplitz operators Tφ with rational symbols φ. We characterize (m, C)-isometric Toeplitz operators Tφ by properties of the rational symbols φ. Moreover, we provide a concrete description of the
-isometric block Toeplitz operators.
