1	Structure of Toeplitz-composition operators Syu, Meng-Syun 14 February 2011 (has links) Let $vp$ be a $L^infty$ function on the unit circle $Bbb T$ and $ au$ be an elliptic automorphism on the unit disc $Bbb D$. In this paper, we will show that $T_vp C_ au$, i.e., the product of the Toeplitz operator $T_vp$ and the composition operator $C_ au$ on $H^2$, is similar to a block Toeplitz matrix if $ au$ has finite order. block Toeplitz Toeplitz block matrix Toeplitz operator block Toeplitz matrix
