Abstract

In this paper, we study necessary and sufficient conditions for the hyponormality of Toeplitz operators with some non-harmonic symbols on the generalized derivative Hardy space. Moreover, we characterize the expansivity and contractivity of Toeplitz operators with such symbols on the generalized derivative Hardy space.
