The classical Chernoff bounds concern the sum of independent, nonnegative, and uniformly bounded random variables. In the matrix setting, the analogous theorem concerns a sum of positive-semidefinite random matrices subjected to a uniform eigenvalue bound. Matrix Chernoff I.

As a result the best known lower bounds for the chromatic number are spectral , and in this paper we improve these bounds by incorporating all eigenvalues. We also conjecture a relationship between the sign of the eigenvalues and the chromatic number, which if true could lead to further developments in spectral graph by: for eigenvalues of Hermitian matrices when the perturbation is Hermitian of rank one. Before describing an application that requires such bounds, we mention that algorithms for computing eigenvalues and eigenvectorsof Hermitian matrices modiﬁed by a rank one matrix are well established [3, 10, 14], [11, §, §]; and that the.

Novel bounds are proposed for the extreme and lower half eigenvalues of the solution matrix for the algebraic Riccati equation. The formulae giving these bounds can easily be applied to determine the region where the eigenvalues lie, and the bounds have the added advantage of being sharper in some cases than the previously proposed ones, as some realistic examples will by: 8.

Upper and lower bounds are derived for the absolute values of the eigenvalues of a matrix polynomial (or λ-matrix). The bounds are based on norms of the coefﬁcient matrices and involve the inverses of the leading and trailing coefﬁcient matrices.

The eigenvalues of the kernel matrix play an important role in a number of kernel methods, in particular, in kernel principal component analysis. It is well known that the eigenvalues of the kernel matrix converge as the number of samples tends to Bounds for the eigenvalues of a matrix book L BraunMikio.

The resulting improvement is more important in the matrix case, since computing eigenvalues of matrix polynomials is significantly more difficult than computing polynomial zeros.

Among others, bounds on such eigenvalues are useful in their computation by iterative methods and when computing pseudospectra. We first illustrate our result by Cited by: 7.

For two Hermitian matrices A and B, at least one of which is positive semidefinite, we give upper and lower bounds for each eigenvalue of AB in terms of the eigenvalues of A and B.

The key aspect we want to stress out is that all these bounds are File Size: KB. In mathematics, an eigenvalue perturbation problem is that of finding the eigenvectors and eigenvalues of a system that is perturbed from one with known eigenvectors and eigenvalues. This is useful for studying how sensitive the original system's eigenvectors and eigenvalues are to changes in the system.

This type of analysis was popularized by Lord Rayleigh, in his investigation of harmonic. The bounds are found by independent calculations on the elements, and, for certain element types, are independent of mesh irregularity. We give examples of when some of the bounds are attained. These results indicate that the preconditioned conjugate-gradient method is appropriate and very rapid for the solution of Galerkin mass-matrix by: Matrix Concentration Bounds In applications, it is common that a random matrix can be expressed as a sum of independent random matrices.

For example, the covariance of X 2 Rn⇥d can be written as XTX = Pn i=1 x T i xi where xi denotes i-th row of X. In this section, we state two common bounds on random matrices. Matrix Chernoff.

These relations immediately imply that any lower bound on μ 1 (G) is a valid lower bound on q 1 (G) and that doubling any lower bound on λ 1 (G) also yields a valid lower bound on q 1 (G).Cited by: texts All Books All Texts latest This Just In Smithsonian Libraries FEDLINK Lower bounds for the rank and location of the Eigenvalues of a matrix Item Preview Lower bounds for the rank and location of the Eigenvalues of a matrix by Fan, Ky; Hoffman, A.
