B-Matrices and Doubly B-Matrices in the Interval Setting
In this paper we focus on generalizing B-matrices and doubly B-matrices into interval setting, including some results regarding these classes. By interval B-matrix, or doubly B-matrix we understand such an inte...

Explicit Inverse of an Interval Matrix with Unit Midpoint
Explicit formulae for the inverse of an interval matrix of the form [I -D, I +D] (where I is the unit matrix) are proved via finding explicit solutions of certain nonlinear matrix equations....

On relation between P-matrices and regularity of interval matrices
We explore new results between P-matrix property and regularity of interval matrices. In particular, we show that an interval matrix is regular in and only if some also investigate the converse direction. We reduce...

Interval matrices: Regularity generates singularity
It is proved that regularity of an interval matrix implies singularity of four related interval matrices. The result is used to prove that for each nonsingular point matrix A, either A or A^-1 can be brought to a s...

A Characterization of Strong Regularity of Interval Matrices
As the main result of this paper it is proved that an interval matrix is strongly regular if and only if certain the matrix inequality has a solution. Several consequences of this result are drawn....

An Eigenvalue Symmetric Matrix Contractor
We propose an eigenvalue contractor for symmetric matrices. Given a symmetric interval matrix A and an interval approximation of its eigenvalue sets the contractor reduces the entries of A such that no matrix with ...
