Interval hulls of $N$ -matrices and almost $P$ -matrices

Projesh Nath Choudhury, M. Rajesh Kannan

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…

Sign non-reversal property for totally non-negative and totally positive matrices, and testing total positivity of their interval hull

Projesh Nath Choudhury, M. Rajesh Kannan, Apoorva Khare

A matrix $A$ is totally positive (or non-negative) of order $k$ , denoted $T P_{k}$ (or $T N_{k}$ ), if all minors of size $\leq k$ are positive (or non-negative). It is well-known that su…
