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.

EA/AE-Eigenvectors of Interval Max-Min Matrices
Mathematics, 2020 Systems working in discrete time (discrete event systems, in short: DES)—based on binary operations: the maximum and the minimum—are studied in so-called max–min (fuzzy) algebra.

Interval observers design for systems with ostensible Metzler system matrices
Frontiers in Aerospace Engineering, 2023 This paper attempts to resolve the problem concerning the interval observers design for linear systems with ostensible Metzler system matrices. Because system dynamics matrices are partially different from strictly Metzler structures, a solution is ...

A different view on controllability and observability of continuous time linear systems with interval coefficients [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2020 We discuss the controllability and observability of time-invariant (continuous time) linear systems with interval coefficients using the notion of being full rank of interval matrices.
