Description: |
In qualitative and combinatorial matrix theory, a methodology based on the use of combinatorial information such as the signs of the elements of a matrix is very often useful in the study of some properties of matrices. A matrix whose entries are chosen from the set {+,-,0} is called a sign pattern matrix. In this talk, we will address the classes of N-matrices, P-matrices, M-matrices, P_0-matrices and inverse M-matrices and the related admissibility of sign pattern matrices problems.
