Linear Equations over cones and Collatz-Wielandt numbers

Bit-Shun Tam, Hans Schneider

Let $K$ be a proper cone in $\IR^n$, let $A$ be an $n \times n$ real matrix that satisfies $A K \subseteq K$ , let $b$ be a given vector of $K$ , and let $λ$ be a given positive real nu…

On the invariant faces associated with a cone-preserving map

Bit-Shun Tam, Hans Schneider

For an $n \times n$ nonnegative matrix $P$ , an isomorphism is obtained between the lattice of initial subsets (of $1, ..., n$ ) for $P$ and the lattice of $P$ -invariant faces of the…
