论文摘要
我们建立了Szegő的距离公式和Widom定理的版本，以在一类有限的统一代数的有限的conimentimension子代数中（通过施加有限数量的线性约束来获得）的（toeplitz家族）的可逆性。每个这样的代数自然都代表着一个繁殖的内核希尔伯特空间，这些空间在证明中起着核心作用。
We establish versions of Szegő's distance formula and Widom's theorem on invertibility of (a family of) Toeplitz operators in a class of finite codimension subalgebras of uniform algebras, obtained by imposing a finite number of linear constraints. Each such algebra is naturally represented on a family of reproducing kernel Hilbert spaces, which play a central role in the proofs.
