Asymptotic behavior of variable Toeplitz matrices

Variable Toeplitz matrices are generated by functions of two variables and share with common Toeplitz matrices a few important properties which come on light considering the algebra generated by sequences of such matrices. These considerations allow to deduce Szegö type theorems which asymptotically describe the distribution of the eigenvalues.
