| 摘 要： | In this paper, we study the unilateral weighted shift which is unitarily equivalent to a Toeplitz operator and prove a similar result to that in 1 ] without the hypothesis that the shift must be hyponormal. As a corollary, we show that if the weight sequence {an}n=0∞ of the shift is convergent, then 1-an2=(1-a02)n+1 ?n≥0
