On lacunary Toeplitz determinants
By using Riemann–Hilbert problem based techniques, we obtain the asymptotic expansion of lacunary Toeplitz determinants detN [ cla−mb [ f ] ] generated by holomorhpic symbols, where la = a (resp. mb = b) except for a finite subset of indices a = h1, . . . , hn (resp. b = t1, . . . , tr). In addition to the usual Szegö asymptotics, our answer involves a determinant of size n + r.
متن کاملBlock - Toeplitz Determinants
We evaluate the Geiss-Leclerc-Schröer φ-map for shape modules over the preprojective algebra Λ of type c A1 in terms of matrix minors arising from the block-Toeplitz representation of the loop group SL2(L). Conjecturally these minors are among the cluster variables for coordinate rings of unipotent cells within SL2(L). In so doing we compute the Euler characteristic of any generalized flag vari...
متن کاملToeplitz determinants with perturbations in the corners
The paper is devoted to exact and asymptotic formulas for the determinants of Toeplitz matrices with perturbations by blocks of fixed size in the four corners. If the norms of the inverses of the unperturbed matrices remain bounded as the matrix dimension goes to infinity, then standard perturbation theory yields asymptotic expressions for the perturbed determinants. This premise is not satisfi...
متن کاملSchatten norms of Toeplitz matrices with Fisher-Hartwig singularities
The asymptotics of the Schatten norms of finite Toeplitz matrices generated by functions with a Fisher-Hartwig singularity are described as the matrix dimension n goes to infinity. The message of the paper is to reveal some kind of a kink: the pth Schatten norm increases as n to the power 1/p before the singularity reaches a critical point and as n to an exponent depending on the singularity be...
متن کاملLattice Theory and Toeplitz Determinants
This is a survey of our recent joint investigations of lattices that are generated by finite Abelian groups. In the case of cyclic groups, the volume of a fundamental domain of such a lattice is a perturbed Toeplitz determinant with a simple Fisher-Hartwig symbol. For general groups, the situation is more complicated, but it can still be tackled by pure matrix theory. Our main result on the lat...
