Stefano De Marchi, Konstantin Usevich
We prove that for almost square tensor product grids and certain sets of bivariate polynomials the Vandermonde determinant can be factored into a product of univariate Vandermonde…

Factorization approach to structured low-rank approximation with applications
Mariya Ishteva, Konstantin Usevich, Ivan Markovsky
We consider the problem of approximating an affinely structured matrix, for example a Hankel matrix, by a low-rank matrix with the same structure. This problem occurs in system ide…
