Sumin Kim, Jongrak Lee
  • General Mathematics


In this article, we present some necessary or sufficient conditions for the hyponormality of Toeplitz operator

T φ {T}_{\varphi }
on the Bergman space
A 2 ( D ) {A}^{2}\left({\mathbb{D}})
. In particular, we consider the Toeplitz operator
T φ {T}_{\varphi }
with nonharmonic symbols
φ \varphi
under certain assumptions.
