Asymptotics of the smallest singular value of a class of toeplitz–generated matrices and related finite rank perturbations
(Springer Link, 2013)Square matrices of the form Xn = Tn+fn(T −1 n ) ∗ , where Tn is an n×n invertible banded Toeplitz matrix and fn some positive sequence are considered. The norms of their inverses are described asymptotically as their ... -
A peculiar permutation phenomenon arising from the singular vector entries of a special class of Toeplitz matrices
(Elsevier, 2014)A special Toeplitz matrix of the form View the MathML sourceTn(fn)=T0,n+fn(T0,n−1)⁎, where T0,nT0,n is the n×nn×n Toeplitz matrix with ones on the diagonal and negative ones on the first upper diagonal, and fnfn some ...
