A recursive condition for the symmetric nonnegative inverse eigenvalue problem
In this paper we present a sufficient ondition and a necessary condition for Symmetri Nonnegative Inverse Eigenvalue Problem. This condition is independent of the existing realizability criteria.

Non symmetric random walk on infinite graph [PDF]
We investigate properties of a non symmetric Markov's chain on an infinite graph. We show the connection with matrix valued random walk polynomials which satisfy the orthogonality formula with respect to non a symmetric matrix valued measure.

The derivative of an orthogonal matrix of eigenvectors of a symmetric matrix
AbstractThe authors supply the derivative of an orthogonal matrix of eigenvectors of a real symmetric matrix. To illustrate the applicability of their result they consider a real symmetric random matrix for which a more or less standard convergence in distribution is assumed to hold.

In this paper we present equivalent characterizations of k-Kernel symmetric Matrices. Necessary and sufficient conditions are determined for a matrix to be k-Kernel Symmetric. We give some basic results of kernel symmetric matrices.

Cauchy's interlace theorem and lower bounds for the spectral radius
We present a short and simple proof of the well-known Cauchy interlace theorem. We use the theorem to improve some lower bound estimates for the spectral radius of a real symmetric matrix.

Generating Polynomials and Symmetric Tensor Decompositions [PDF]
This paper studies symmetric tensor decompositions. For symmetric tensors, there exist linear relations of recursive patterns among their entries. Such a relation can be represented by a polynomial, which is called a generating polynomial.

Symmetric matrix pencils: codimension counts and the solution of a pair of matrix equations
The set of all solutions to the homogeneous system of matrix equations (X-T A + AX, X-T B + BX) = (0, 0), where (A, B) is a pair of symmetric matrices of the same size, is characterized.

Unitary equivalence to a complex symmetric matrix: a modulus criterion [PDF]
We develop a procedure for determining whether a square complex matrix is unitarily equivalent to a complex symmetric (i.e., self-transpose) matrix. Our approach has several advantages over existing methods.

AbstractA significant number of matrix eigenvalue problems, quadratic or linear, are best reformulated as pencils (A, M) in which both A and M are real and symmetric. Some examples are given and then the canonical forms are re-examined to explain the role of the sign characteristic attached to real eigenvalues. In addition we examine the limitations on

The distribution of symmetric matrix quotients
AbstractPhillips (J. Multivariate Anal. 16 (1985) 157) generalizes Cramer's (Mathematical Methods of Statistics, Princeton University Press, Princeton, NJ, 1946) inversion formula for the distribution of a quotient of two scalar random variables to the matrix quotient case. However, he gives the result for the asymmetric matrix quotient case. This note
