متن کاملSubmatrices of Hadamard matrices: complementation results
Two submatrices A,D of a Hadamard matrix H are called complementary if, up to a permutation of rows and columns, H = [
متن کاملReconstruction of matrices from submatrices
For an arbitrary matrix A of n×n symbols, consider its submatrices of size k×k, obtained by deleting n−k rows and n−k columns. Optionally, the deleted rows and columns can be selected symmetrically or independently. We consider the problem of whether these multisets determine matrix A. Following the ideas of Krasikov and Roditty in the reconstruction of sequences from subsequences, we replace t...
متن کاملNon-Self-Adjoint Toeplitz Matrices Whose Principal Submatrices Have Real Spectrum
We introduce and investigate a class of complex semi-infinite banded Toeplitz matrices satisfying the condition that the spectra of their principal submatrices accumulate onto a real interval when the size of the submatrix grows to ∞. We prove that a banded Toeplitz matrix belongs to this class if and only if its symbol has real values on a Jordan curve located in C\{0}. Surprisingly, it turns ...
متن کاملSubmatrices of Four Dimensional Summability Matrices
In this paper, we show that a matrix that maps l ′′ into l ′′ can be obtained from any RH-regular matrix by the deletion of rows. Also a four dimensional conservative matrix can be obtained by the deletion of rows from a matrix that preserves boundedness. We will use these techniques to derive a sufficient condition for a four dimensional matrix to sum an unbounded sequence. RESUMEN En este tra...
