Bounds on norms of the adjoint matrix

چکیده
An upper bound on operator norms of the adjoint matrix is presented, and special cases of the l 1 , l 2 and l 1 norms are investigated. The results are then used to obtain lower bounds on the smallest absolute value of an eigenvalue of a nonsingular matrix.

Error bounds in approximating n-time differentiable functions of self-adjoint operators in Hilbert spaces via a Taylor's type expansion
On utilizing the spectral representation of selfadjoint operators in Hilbert spaces, some error bounds in approximating $n$-time differentiable functions of selfadjoint operators in Hilbert Spaces via a Taylor's type expansion are given.
متن کاملStabilization of Linear Systems with Prescribed Transient Bounds
The feedback synthesis of linear systems satisfying certain exponential bounds on their transient behavior is studied. We present sufficient conditions ensuring that there exists a state feedback matrix such that the closed loop system satisfies a desired exponential growth bound. Special interest is directed to the case of generating contraction semigroups, which under certain conditions can b...

An upper bound on operator norms of compound matrices is presented and special cases that involve the l l and l norms are investigated The results are then used to obtain bounds on products of the largest or smallest eigenvalues of a matrix The research was started while the rst author visited the Technion in It was continued during a visit of the second author at Universit at Bielefeld and at ...
متن کاملIdentifying Useful Variables for Vehicle Braking Using the Adjoint Matrix Approach to the Mahalanobis-Taguchi System
The Mahalanobis Taguchi System (MTS) is a diagnosis and forecasting method for multivariate data. Mahalanobis distance (MD) is a measure based on correlations between the variables and different patterns that can be identified and analyzed with respect to a base or reference group. MTS is of interest because of its reported accuracy in forecasting small, correlated data sets. This is the type o...
متن کاملUpper and lower bounds for numerical radii of block shifts
For an n-by-n complex matrix A in a block form with the (possibly) nonzero blocks only on the diagonal above the main one, we consider two other matrices whose nonzero entries are along the diagonal above the main one and consist of the norms or minimum moduli of the diagonal blocks of A. In this paper, we obtain two inequalities relating the numeical radii of these matrices and also determine ...
