On Pointwise Smooth Dendroids

open access: yesRevista Integración, 2022
This is a survey paper on dendroids, smooth dendroids, and mainly on pointwise smooth dendroids based on the work of J. J. Charatonik and C. Eberhart (dendroids and smooth dendroids) and S. T. Czuba (pointwise smooth dendroids).

Dendroidal sets [PDF]

open access: yesAlgebraic & Geometric Topology, 2007
We introduce the concept of a dendroidal set. This is a generalization of the notion of a simplicial set, specially suited to the study of operads in the context of homotopy theory. We define a category of trees, which extends the category $Δ$ used in simplicial sets, whose presheaf category is the category of dendroidal sets.

Atlantia, a new genus of Dendrophylliidae (Cnidaria, Anthozoa, Scleractinia) from the eastern Atlantic [PDF]

open access: yesPeerJ, 2020
Atlantia is described as a new genus pertaining to the family Dendrophylliidae (Anthozoa, Scleractinia) based on specimens from Cape Verde, eastern Atlantic. This taxon was first recognized as Enallopsammia micranthus and later described as a new species,

Diagenesis of the microbialites in the Permian–Triassic boundary section at Laolongdong, Chongqing, South China

open access: yesJournal of Palaeogeography, 2013
An interval of limestone, which generally has a dendroid appearance on outcrops, has been found in several Permian–Triassic boundary (PTB) sections in South China, and interpreted to be microbialites.

Multigene phylogeny reveals a cryptic diversity in the genus Dinobryon (Chrysophyceae) with integrative description of five new species

open access: yesFrontiers in Plant Science, 2023
IntroductionThe genus Dinobryon is one of the most recognizable chrysophyte genera, characterized by dendroid colonies with a biflagellate inside each cellulosic lorica. The representative forms of lorica are cylindrical, conical, vase, or funnel shaped,

On dendroids with Kelley’s property [PDF]

open access: yesProceedings of the American Mathematical Society, 1988
It is proved that if a dendroid has Kelley’s property, then it is smooth. This is a correction of an error from [ 4 ].

Dendroidal Sets

open access: yes, 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.

Dendroids and preorders

open access: yesGlasnik 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.
