In the past several decades the classical Perron–Frobenius theory for nonnegative matrices has been extended to obtain remarkably precise and beautiful results for classes of nonlinear maps. This nonlinear Perron–Frobenius theory has found signif

We show that if$$Y_j\subset \mathbb {C}^{n_j}$$Yj⊂Cnjis a bounded strongly convex domain with$$C^3$$C3-boundary for$$j=1,\dots ,q$$j=1,⋯,q, and$$X_j\subset \mathbb {C}^{m_j}$$Xj⊂Cmjis a bounded convex domain for$$j=1,\ldots ,p$$j=1,…,p, then

A basic problem in the theory of partially ordered vector spaces is to characterise those cones on which every order-isomorphism is linear. We show that this is the case for every Archimedean cone that equals the inf-sup hull of the sum of its engage

We study the global topology of the horofunction compactification of smooth manifolds with a Finsler distance. The main goal is to show, for certain classes of these spaces, that the horofunction compactification is naturally homeomorphic to the clos

In this paper we prove a recent conjecture by M. Hirsch, which says that if $(f,\Omega)$ is a discrete time monotone dynamical system, with $f\colon \Omega\to\Omega$ a homeomorphism on an open connected subset of a finite dimensional vector space, an

In this paper we extend results by De la Harpe concerning the isometries of strictly convex Hilbert geometries, and the characterisation of the isometry groups of Hilbert geometries on finite dimensional simplices, to infinite dimensions. The proofs

In this paper a geometric characterization of the unique geodesics in Thompson's metric spaces is presented. This characteriza- tion is used to prove a variety of other geometric results. Firstly, it will be shown that there exists a unique Thompson'

The famous Koecher-Vinberg theorem characterizes the Euclidean Jordan algebras among the finite dimensional order unit spaces as the ones that have a symmetric cone. Recently Walsh gave an alternative characterization of the Euclidean Jordan algebras

We show that the Riesz completion of an Archimedean partially ordered vector space $$X$$ with unit can be represented as a norm dense Riesz subspace of the smallest functional representation of $$X.$$ This yields a convenient way to find the Riesz co
