Local Convergence of Proximal Splitting Methods for Rank Constrained Problems
, 2017 We analyze the local convergence of proximal splitting algorithms to solve optimization problems that are convex besides a rank constraint. For this, we show conditions under which the proximal operator of a function involving the rank constraint is ...

Proceedings of the American Mathematical Society, 1967 In a partially ordered ring, the convex ideals are of special interest because their quotient rings possess a naturally induced order [3, 5.2]. Some partially ordered rings have an abundance of convex ideals; for instance, every prime ideal in the ring of all continuous real-valued functions on a topological space is convex (with respect to the usual ...

, 2013 Convex cycles play a role e.g. in the context of product graphs. We introduce convex cycle bases and describe a polynomial-time algorithm that recognizes whether a given graph has a convex cycle basis and provides an explicit construction in the positive

Hyperspace of convex compacta of nonmetrizable compact convex subspaces of locally convex spaces
, 2008 Our main result states that the hyperspace of convex compact subsets of a compact convex subset $X$ in a locally convex space is an absolute retract if and only if $X$ is an absolute retract of weight $\le\omega_1$.

Advanced Engineering Materials, EarlyView.A multimaterial approach is introduced to improve upon auxetic structures by combining two different polymers into the same reentrant honeycomb structure via additive manufacturing. The deformation behavior as well as the resulting Poisson's ratio are thereby improved significantly.

2D approximately reciprocal ρ-convex functions and associated integral inequalities
AIMS Mathematics, 2020 The main objective of this article is to introduce the notion of 2D approximately reciprocal ρ-convex functions, show that this class of functions unifies several other unrelated classes of reciprocal convex functions, obtain several new refinements of ...

Finite convex geometries of circles [PDF]
, 2013 Let F be a finite set of circles in the plane. We point out that the usual convex closure restricted to F yields a convex geometry, that is, a combinatorial structure introduced by P. H Edelman in 1980 under the name "anti-exchange closure system".
