A unified approach to nonlinear Perron-Frobenius theory

Brian Lins

Let $f : R_{> 0}^{n} \to R_{> 0}^{n}$ be an order-preserving and homogeneous function. We show that the set of eigenvectors of $f$ in $R_{> 0}^{n}$ is none…

Nonexpansive maps with surjective displacement

Brian Lins

We investigate necessary and sufficient conditions for a nonexpansive map $f$ on a Banach space $X$ to have surjective displacement, that is, for $f - id$ to map onto $X$ .…
