Asymptotic behavior of solutions of fully nonlinear equations over exterior domains
Comptes Rendus. Mathématique, 2021 In this paper, we consider the asymptotic behavior at infinity of solutions of a class of fully nonlinear elliptic equations $F(D^2u)=f(x)$ over exterior domains, where the Hessian matrix $(D^2u)$ tends to some symmetric positive definite matrix at ...

Even grade generic skew-symmetric matrix polynomials with bounded rank [PDF]
arXiv, 2023 We show that the set of $m \times m$ complex skew-symmetric matrix polynomials of even grade $d$, i.e., of degree at most $d$, and (normal) rank at most $2r$ is the closure of the single set of matrix polynomials with certain, explicitly described, complete eigenstructure.

IS THE QUARK-MIXING MATRIX MODULI SYMMETRIC? [PDF]
Modern Physics Letters A, 2004 If the unitary quark-mixing matrix, V, is moduli symmetric, it will depend on three real parameters. This means that there is a relation between the four parameters needed to parametrize a general V. It is shown that there exists a very simple relation involving |V11|2, |V33|2, [Formula: see text] and [Formula: see text].

DECOMPOSITION METHOD FOR SOLVING FULLY FUZZY LINEAR SYSTEMS [PDF]
Iranian Journal of Optimization, 2010 In this paper, we investigate the existence of a positive solution of fully fuzzy linear equation systems. This paper mainly to discuss a new decomposition of a nonsingular fuzzy matrix, the symmetric times triangular (ST) decomposition.

A note on multilevel Toeplitz matrices
Special Matrices, 2019 Chien, Liu, Nakazato and Tam proved that all n × n classical Toeplitz matrices (one-level Toeplitz matrices) are unitarily similar to complex symmetric matrices via two types of unitary matrices and the type of the unitary matrices only depends on the ...

Partially Ordered Group of the 2×2 Symmetric Matrices
InPrime, 2019 This paper deals with the partially ordered group of the 2×2 symmetric matrices. A matrix is defined to be a positive if each entry of the matrix is positive. With the characterization of the 2×2 symmetric matrix, we construct the positive cone such that

On the Spectrum of Random Anti-symmetric and Tournament Matrices [PDF]
Random Matrices: Theory Appl. 05, 1650010 (2016), 2014 We consider a discrete, non-Hermitian random matrix model, which can be expressed as a shift of a rank-one perturbation of an anti-symmetric matrix. We show that, asymptotically almost surely, the real parts of the eigenvalues of the non-Hermitian matrix around any fixed index remain interlaced with those of the anti-symmetric matrix. Along the way, we

Random matrix theory and symmetric spaces [PDF]
Physics Reports, 2004 In this review we discuss the relationship between random matrix theories and symmetric spaces. We show that the integration manifolds of random matrix theories, the eigenvalue distribution, and the Dyson and boundary indices characterizing the ensembles are in strict correspondence with symmetric spaces and the intrinsic characteristics of their ...
