B^R_π-Matrices, B-Matrices, and Doubly B-Matrices in the Interval Setting

In this paper we focus on generalizing B π R -matrices into the interval setting, including some results regarding class. There are two possible ways to generalize but will prove that, in a sense, they one. We derive mainly means of recognition for matrices class, such as characterizations, necessary conditions and sufficient ones. Next take look at B -matrices doubly -matrices, which were introduced recently, present their characterizations through reduction, well characterization -matrices.
