Cuntz-Toeplitz代数E_{n+1}$（n\geq 1 $）是由n+1$个值域相互正交的等距生成的泛C*-代数。本文研究了Cuntz-Toeplitz代数的自同构群，并确定了它们的同伦群。
The Cuntz-Toeplitz algebra $E_{n+1}$ for $n\geq1$ is the universal C*-algebra generated by $n+1$ isometries with mutually orthogonal ranges. In this paper, we investigate the automorphism groups of the Cuntz-Toeplitz algebras and determine their homotopy groups.
