Determinants of Interval Matrices [PDF]
The Electronic Journal of Linear Algebra, 2018 In this paper we shed more light on determinants of interval matrices. Computing the exact bounds on a determinant of an interval matrix is an NP-hard problem. Therefore, attention is first paid to approximations.

Gershgorin disk theorem in complex interval matrices [PDF]
Proceedings of the Estonian Academy of Sciences, 2022 In this article, the Gershgorin disk theorem in complex interval matrices is proposed for enclosing interval eigenvalues. This is a non-iterative method for finding eigenvalue bounds for both real and imaginary parts.

A Fast Algorithm for the Eigenvalue Bounds of a Class of Symmetric Tridiagonal Interval Matrices
AppliedMath, 2023 The eigenvalue bounds of interval matrices are often required in some mechanical and engineering fields. In this paper, we improve the theoretical results presented in a previous paper “A property of eigenvalue bounds for a class of symmetric tridiagonal

Interval Valued Secondary k-Range Symmetric Neutrosophic Fuzzy Matrices [PDF]
Neutrosophic Sets and Systems, 2023 The characterization of interval valued (IV) secondary k-range symmetric (RS) Neutrosophic fuzzy matrices have been examined in this study with an example. It is discussed how IV s-k RS, s-RS, IV k-RS, and IV RS matrices relate to one another.

On Stability of Interval Matrices [PDF]
1993 American Control Conference, 1993 New sufficient, and sometimes necessary and sufficient conditions, are obtained for Schur- and Hurwitz-stability of interval matrices by relying on the concept of connective stability and M-matrices. The necessity part is broadened to include interval matrices with mixed signs of the off-diagonal elements, provided the sign patterns follow that of the ...

Interval hulls of N-matrices and almost P-matrices [PDF]
Linear Algebra and its Applications, 2021 We establish a characterization of almost $P$-matrices via a sign non-reversal property. In this we are inspired by the analogous results for $N$-matrices. Next, the interval hull of two $m \times n$ matrices $A=(a_{ij})$ and $B = (b_{ij})$, denoted by $\mathbb{I}(A,B)$, is the collection of all matrices $C \in \mathbb{R}^{m \times n}$ such that each ...

An Overview of Polynomially Computable Characteristics of Special Interval Matrices [PDF]
Studies in Computational Intelligence, 2017 It is well known that many problems in interval computation are intractable, which restricts our attempts to solve large problems in reasonable time. This does not mean, however, that all problems are computationally hard.
