Glasnik matematički, 2003 Let X be a dendroid and x* X. 0(X, x*) will denote the preordered set of arc-components of X \ {x*}, where the preorder is defined by if cl(). In this paper we investigate conditions under which there exists a pair (X,x*) such that 0(X, x*) is isomorphic to a given preordered set.

Rigidification of dendroidal infinity-operads [PDF]
Homology, Homotopy and Applications, 2021 We give an explicit description of the rigidification of an $\infty$-operad as a simplicial operad. This description is based on the notion of dendroidal necklace, extending work of Dugger and Spivak from the categorical context to the operadic context, although with a different framework, which relates constructions involving necklaces to a standard ...

Rivista Italiana di Paleontologia e Stratigrafia, 2007 The Cretaceous coral genus Preverastraea is being revised, mainly on the basis of sample material. This cerioid, occasionally astreoid or phaceloid, genus is characterised by round or polygonal calices, compact septa in a regular hexameral symmetry and ...

Dendroidal Segal spaces and ∞-operads [PDF]
Journal of Topology, 2013 We introduce the dendroidal analogues of the notions of complete Segal space and of Segal category, and construct two appropriate model categories for which each of these notions corresponds to the property of being fibrant. We prove that these two model categories are Quillen equivalent to each other, and to the monoidal model category for 8-operads ...

, 2019 The Cordillera del Cóndor on the border between Ecuador and Peru stands out because of its rich biodiversity and high endemism. Here we describe a new dendroid species of the thalloid liverwort genus Riccardia, R. verticillata Gradst.

, 2022 AbstractIn this chapter we will introduce the category of dendroidal sets, which is the main object of study of this book. The definition of a dendroidal set mirrors that of a simplicial set, except that the category Δ is replaced by a larger category Ω of trees.

Dendroid peptide structural mimetics of omega-conotoxin MVIIA based on a 2(1H)-quinolinone core [PDF]
, 2000 Three mimetics of the peptide -Conotoxin MVIIA have been synthesised following the dendroid approach. The three key central amino acids of the natural peptide are mimicked by phenylguanidine (arginine), isopentyl (leucine) and aryl alcohol (tyrosine ...

Simplicial and Dendroidal Homotopy Theory
, 2022 This open access book offers a self-contained introduction to the homotopy theory of simplicial and dendroidal sets and spaces. These are essential for the study of categories, operads, and algebraic structure up to coherent homotopy. The dendroidal theory combines the combinatorics of trees with the theory of Quillen model categories.

Acta Agrobotanica, 2014 Origanum dictamnus is a seasonally dimorphic plant having different appearance in winter and summer. Shoots of winter plants are leaf-naked except for their apical region which bears a cluster of small leaves covered with a thick indumentum of non ...

Contractibility of the hyperspace of meager subcontinua, two examples
Applied General TopologyGiven 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 ...
