Approximation of Dendroids by Trees

open access: yes, 2008
We prove that, for every dendroid X, every tree To contained in X and every e \u3e 0, there exists a tree T, contained in X and containing To and an epslion-retraction of X onto T.

Mappings on weakly arcwise open dendroids

open access: yes, 1998
A dendroid X is said to be weakly arcwise open (WAO) at p ∈ X if each arc component of X \ {p} is either open or has empty interior. Thew dendroid X is WAO if it is WAO at p for each p ∈ X.

On the equivalence of Lurie's ∞-operads and dendroidal ∞-operads

open access: yesJournal of Topology
In this paper, we prove the equivalence of two symmetric monoidal (Formula presented.) -categories of (Formula presented.) -operads, the one defined in Lurie [Higher algebra, available at the author's homepage, http://math.ias.edu/~lurie/, September 2017 version] and the one based on dendroidal spaces.

Mass occurrence of planktic dendroid graptolite synrhabdosomes (Calyxdendrum) from the Early Ordovician Fezouata biota of Morocco: Graptolite synrhabdosomes Fezouata biota

open access: yes
The genus Calyxdendrum is here revised to include planktic dendroid graptolites from the Ordovician (Tremadocian to Sandbian). The mass occurrence of Calyxdendrum amicabilis n. sp.
