【 摘 要 】
We describe the C*-algebra associated with the finite sections discretization of truncated Toeplitzoperators on the model space K2u where u is an infinite Blaschke product. As consequences, we get a stabilitycriterion for the finite sections discretization and results on spectral and pseudospectral approximation.
