Abstract
In this paper, we study the hyponormal Toeplitz operators Tφ, where φ is a trigonometric polynomial symbol with finite degree. We present necessary and sufficient conditions for the hyponormality of Tφ under some assumptions about the coefficients of φ. Next, we find the necessary condition for hyponormality of Tφ.
