Non-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 کاملNoncirculant Toeplitz Matrices All of Whose Powers Are Toeplitz
Let a, b and c be fixed complex numbers. Let Mn(a, b, c) be the n×n Toeplitz matrix all of whose entries above the diagonal are a, all of whose entries below the diagonal are b, and all of whose entries on the diagonal are c. For 1 6 k 6 n, each k × k principal minor of Mn(a, b, c) has the same value. We find explicit and recursive formulae for the principal minors and the characteristic polyno...

متن کاملConstructing all self-adjoint matrices with prescribed spectrum and diagonal
The Schur-Horn Theorem states that there exists a self-adjoint matrix with a given spectrum and diagonal if and only if the spectrum majorizes the diagonal. Though the original proof of this result was nonconstructive, several constructive proofs have subsequently been found. Most of these constructive proofs rely on Givens rotations, and none have been shown to be able to produce every example...
متن کاملSpectral Properties of Random Non-self-adjoint Matrices and Operators
We describe some numerical experiments which determine the degree of spectral instability of medium size randomly generated matrices which are far from self-adjoint. The conclusion is that the eigenvalues are likely to be intrinsically uncomputable for similar matrices of a larger size. We also describe a stochastic family of bounded operators in infinite dimensions for almost all of which the ...
