On the characteristic polynomial of matrices with prescribed columns and the stabilization and observability of linear systems
Let A 2 F , B 2 F , where F is an arbitrary eld. In this paper, the possible characteristic polynomials of [A B ], when some of its columns are prescribed and the other columns vary, are described. The characteristic polynomial of [A B ] is de ned as the largest determinantal divisor (or the product of the invariant factors) of [xIn A B ]. This result generalizes a previous theorem by H. Wimmer...
متن کاملSome results on the polynomial numerical hulls of matrices
In this note we characterize polynomial numerical hulls of matrices $A in M_n$ such that$A^2$ is Hermitian. Also, we consider normal matrices $A in M_n$ whose $k^{th}$ power are semidefinite. For such matriceswe show that $V^k(A)=sigma(A)$.

متن کاملCounting Integral Matrices with a given Characteristic Polynomial
We give a simpler proof of an earlier result giving an asymptotic estimate for the number of integral matrices, in large balls, with a given monic integral irreducible polynomial as their common characteristic polynomial. The proof uses equidistributions of polynomial trajectories on SL(n, R)/SL(n, Z), which is a generalization of Ratner’s theorem on equidistributions of unipotent trajectories....
متن کاملThe Characteristic Polynomial of Some Perturbed Tridiagonal k-Toeplitz Matrices
We generalize some recent results on the spectra of tridiagonal matrices, providing explicit expressions for the characteristic polynomial of some perturbed tridiagonal k-Toeplitz matrices. The calculation of the eigenvalues (and associated eigenvectors) follows straightforward. Mathematics Subject Classification: 15A18, 42C05, 33C45
