نویسندگان
چکیده
In this work, the notion of extended eigenvalues a 2 ? lower triangular operator matrix has been researched. More precisely, relations between spectrum with spectrum, point and its diagonal entries have investigated. The obtained results supplemented by examples. addition, some properties block matrices displayed.

Further inequalities for operator space numerical radius on 2*2 operator matrices
We present some inequalities for operator space numerical radius of $2times 2$ block matrices on the matrix space $mathcal{M}_n(X)$, when $X$ is a numerical radius operator space. These inequalities contain some upper and lower bounds for operator space numerical radius.
متن کاملA NOTE VIA DIAGONALITY OF THE 2 × 2 BHATTACHARYYA MATRICES
In this paper, we consider characterizations based on the Bhattacharyya matrices. We characterize, under certain constraint, dis tributions such as normal, compound poisson and gamma via the diago nality of the 2 X 2 Bhattacharyya matrix.
متن کاملIntertwiners of Pseudo-Hermitian 2 × 2-Block-Operator Matrices and a No-Go Theorem for Isospectral MHD Dynamo Operators
Pseudo-Hermiticity as a generalization of usual Hermiticity is a rather common feature of (differential) operators emerging in various physical setups. Examples are Hamiltonians of PTand CPT-symmetric quantum mechanical systems [1] as well as the operator of the spherically symmetric α-dynamo [2] in magnetohydrodynamics (MHD). In order to solve the inverse spectral problem for these operators, ...
متن کاملSpectral Factorization of 2-block Toeplitz Matrices and Refinement Equations
Pairs of 2-block Toeplitz (N×N)-matrices (Ts)ij = p2i−j+s−1, s = 0, 1, i, j ∈ {1, . . . , N}, are considered for arbitrary sequences of complex coefficients p0, . . . , pN . A complete spectral resolution of the matrices T0, T1 in the system of their common invariant subspaces is obtained. A criterion of nondegeneracy and of irreducibility of these matrices is derived, and their kernels, root s...
متن کاملSpectral properties of unbounded JJ-self-adjoint block operator matrices
We study the spectrum of unbounded J-self-adjoint block operator matrices. In particular, we prove enclosures for the spectrum, provide a sufficient condition for the spectrum being real and derive variational principles for certain real eigenvalues even in the presence of non-real spectrum. The latter lead to lower and upper bounds and asymptotic estimates for eigenvalues. AMS Subject classifi...
