Toeplitz matrices and determinants with Fisher-Hartwig symbols
TL;DR: In this article, the Toeplitz matrices generated by symbols of the form a(t) = Φ r=1 R | t−t r | 2α r (− t ) t r β r b(t ) (| t |=1) where t 1,…, t R are pairwise distinct points on the unit circle, b is sufficiently smooth, b (t) ≠ 0 (¦t¦ = 1), and ind b = 0.

On the condition numbers of large semidefinite Toeplitz matrices
TL;DR: Several classes of symbols a are described for which κ ( T n ( a )) increases like (log n ) x, n x , or even e xn .

Weighted norm inequalities
TL;DR: In this paper, it was shown that if Γ is a Carleson curve and w is a weight in A P (Γ) (1
