 A note on hyponormal Toeplitz operators Bull. Korean Math. Soc. 2011 Vol. 48, No. 3, 647-653 https://doi.org/10.4134/BKMS.2011.48.3.647Published online May 1, 2011 An-Hyun Kim Changwon National University Abstract : In this note we are concerned with the hyponormality of Toeplitz operators $T_\phi$ with polynomial symbols $\phi=\bar g+f$ $(f,g\in H^\infty(\Bbb{T}))$ when $g$ divides $f$. Keywords : Toeplitz operators, hyponormal MSC numbers : Primary 47B20, 47B35 Downloads: Full-text PDF
