Vertex decomposability of complexes associated to forests [PDF]

Transactions on Combinatorics, 2022
In this article‎, ‎we discuss the vertex decomposability of three well-studied simplicial complexes associated to forests‎. ‎In particular‎, ‎we show that the bounded degree complex of a forest and the complex of directed trees of a multidiforest is ...

𝜎-Approximately Contractible Banach Algebras

Abstract and Applied Analysis, 2012
We investigate 𝜎-approximate contractibility and 𝜎-approximate amenability of Banach algebras, which are extensions of usual notions of contractibility and amenability, respectively, where 𝜎 is a dense range or an idempotent bounded endomorphism of the ...

Modeling exercise using optogenetically contractible Drosophila larvae

BMC Genomics, 2022
The pathophysiological effects of a number of metabolic and age-related disorders can be prevented to some extent by exercise and increased physical activity.

Fiber Bundle Fault Tolerance of GKP Codes [PDF]

Quantum
We investigate multi-mode GKP (Gottesman–Kitaev–Preskill) quantum error-correcting codes from a geometric perspective. First, we construct their moduli space as a quotient of groups and exhibit it as a fiber bundle over the moduli space of symplectically

A note on edge-disjoint contractible Hamiltonian cycles in polyhedral maps

Electronic Journal of Graph Theory and Applications, 2014
We present a necessary and sufficient condition for existence of edge-disjoint contractible Hamiltonian Cycles in the edge graph of polyhedral maps.

Contractibility of the hyperspace of meager subcontinua, two examples

Applied General Topology
Given a metric continuum X, the hyperspace of meager subcontinua of X, denoted by M(X), is the collection of all subcontinua of X with empty interior. Answering questions by Norberto Ordo˜nez, in this paper we construct two dendroids showing that there ...

Existence of multiple positive solutions for fractional Laplace problems with critical growth and sign-changing weight in non-contractible domains

Boundary Value Problems, 2019
We prove the existence of multiple positive solutions for a fractional Laplace problem with critical growth and sign-changing weight in non-contractible domains.

Levi Contractions and AGM Contractions: A Comparison

Notre Dame Journal of Formal Logic, 1995
Among the AGM postulates for contraction, the one that has been most open to query is that of recovery. In his book: The fixation of belief and its undoing (Cambridge UK, 1991), \textit{Isaac Levi} proposed modifying the AGM partial meet construction for contraction in such a way as to invalidate recovery.
