Iteration of order preserving subhomogeneous maps on a cone [PDF]
, 2006 We investigate the iterative behaviour of continuous order preserving subhomogeneous maps $f: K\,{\rightarrow}\, K$, where $K$ is a polyhedral cone in a finite dimensional vector space. We show that each bounded orbit of $f$ converges to a periodic orbit

Convex Analysis for Minimizing and Learning Submodular Set Functions [PDF]
, 2013 The connections between convexity and submodularity are explored, for purposes of minimizing and learning submodular set functions. First, we develop a novel method for minimizing a particular class of submodular functions, which can be expressed as a

A cone-theoretic barycenter existence theorem [PDF]
Logical Methods in Computer ScienceWe show that every continuous valuation on a locally convex, locally convex-compact, sober topological cone $\mathfrak{C}$ has a barycenter. This barycenter is unique, and the barycenter map $\beta$ is continuous, hence is the structure map of a $\mathbf

Some properties of set-valued sine families [PDF]
Opuscula Mathematica, 2012 Let \(\{F_t : t \geq 0\}\) be a family of continuous additive set-valued functions defined on a convex cone \(K\) in a normed linear space \(X\) with nonempty convex compact values in \(X\). It is shown that (under some assumptions) a regular sine family

Extensions of convex functionals on convex cones [PDF]
Applicationes Mathematicae, 1998 Summary: We prove that under some topological assumptions (e.g. if \(M\) has nonempty interior in \(X\)), a convex cone \(M\) in a linear topological space \(X\) is a linear subspace if and only if each convex functional on \(M\) has a convex extension on the whole space \(X\).

Strong Subjectivism in the Marxian Theory of Exploitation: A Critique [PDF]
This paper critically analyses the strongly subjectivist approach to exploitation theory recently proposed by Matsuo ([7]), in the context of general convex economies with heterogeneous agents.

A note on Gordan's theorem over cone domains
International Journal of Mathematics and Mathematical Sciences, 1982 This note presents a proof of Gordan's Theorem over general closed, convex cone domains which follows in a natural way appealing to the standard definitions of closed convex cones and their respective polar cones.

Advanced Functional Materials, EarlyView.Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...

Cone asymptotes of convex sets
Extracta Mathematicae, 2020 Based on the notion of plane asymptote, we introduce the new concept of cone asymptote of a set in the n-dimensional Euclidean space. We discuss the existence and describe some families of cone asymptotes.

Convex polyhedra with triangular faces and cone triangulation [PDF]
Yugoslav Journal of Operations Research, 2011 Considering the problem of the minimal triangulation for a given polyhedra (dividing polyhedra into tetrahedra) it is known that the cone triangulation provides the number of tetrahedra which is the smallest, or the closest to it.
