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