Configuration spaces and polyhedral products [PDF]
Advances in Mathematics, 2017 This paper aims to find the most general combinatorial conditions under which a moment-angle complex $(D^2,S^1)^K$ is a co-$H$-space, thus splitting unstably in terms of its full subcomplexes. In this way we study to which extent the conjecture holds that a moment-angle complex over a Golod simplicial complex is a co-$H$-space.

Polyhedral Covers of Tree Space [PDF]
SIAM Journal on Discrete Mathematics, 2014 The phylogenetic tree space, introduced by Billera, Holmes, and Vogtmann, is a cone over a simplicial complex. In this short article, we construct this complex from local gluings of classical polytopes, the associahedron and the permutohedron. Its homotopy is also reinterpreted and calculated based on polytope data.

Rethinking polyhedrality for lindenstrauss spaces [PDF]
Israel Journal of Mathematics, 2016 A Banach space is a Lindenstrauss space if its dual is isometric to \(L_1(\mu)\) for some measure \(\mu\); it is polyhedral if the unit balls of its finite-dimensional subspaces are polytopes. In [Proc. Am. Math. Soc. 23, 378--385 (1969; Zbl 0184.15101)], \textit{M.

Optimal synthesis into fixed XX interactions [PDF]
Quantum, 2022 We describe an optimal procedure, as well as its efficient software implementation, for exact and approximate synthesis of two-qubit unitary operations into any prescribed discrete family of XX-type interactions and local gates.

Superbalance of holographic entropy inequalities
Journal of High Energy Physics, 2020 The domain of allowed von Neumann entropies of a holographic field theory carves out a polyhedral cone — the holographic entropy cone — in entropy space. Such polyhedral cones are characterized by their extreme rays.

Towards Efficient Exact Synthesis for Linear Hybrid Systems [PDF]
Electronic Proceedings in Theoretical Computer Science, 2011 We study the problem of automatically computing the controllable region of a Linear Hybrid Automaton, with respect to a safety objective. We describe the techniques that are needed to effectively and efficiently implement a recently-proposed solution ...

AUTOMATIC 3D RECONSTRUCTION OF COMPLEX BUILDINGS FROM INCOMPLETE POINT CLOUDS WITH TOPOLOGICAL-RELATION CONSTRAINTS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Automatic 3D building reconstruction from laser scanning or photogrammetric point clouds has gained increasing attention in the past two decades. Although many efforts have been made, the complexity of buildings and incompletion of point clouds, i.e ...

Metabolic Pathway Analysis in the Presence of Biological Constraints
Computation, 2021 Metabolic pathway analysis is a key method to study a metabolism in its steady state, and the concept of elementary fluxes (EFs) plays a major role in the analysis of a network in terms of non-decomposable pathways.

On polyhedral product spaces over polyhedral joins [PDF]
Homology, Homotopy and Applications, 2018 The construction of a simplicial complex given by polyhedral joins (introduced by Anton Ayzenberg), generalizes Bahri, Bendersky, Cohen and Gitler's $J$-construction and simplicial wedge construction. This article gives a cohomological decomposition of a polyhedral product over a polyhedral join for certain families of pairs of simplicial complexes.
