What is "dendroid"

Dendroid \Den"droid\, Dendroidal \Den*droid"al\, a. [Gr. ? treelike; de`ndron tree + e'i^dos form: cf. F. dendro["i]de.] Resembling a shrub or tree in form; treelike; branching.

Syn: arboreal, arboreous, arborescent, arboresque, arboriform, dendriform, treelike, tree-shaped.

a. Resembling a shrub or tree. n. (context math English) (rfdef: English)

adj. resembling a tree in form and branching structure; "arborescent coral found off the coast of Bermuda"; "dendriform sponges" [syn: arboreal, arboreous, arborescent, arboresque, arboriform, dendriform, dendroidal, treelike, tree-shaped]

In mathematics, a dendroid is type of topological space, satisfying the properties that it is hereditarily unicoherent (meaning that every subcontinuum of X is unicoherent), arcwise connected, and forms a continuum. The term dendroid was introduced by Bronisław Knaster lecturing at the University of Wrocław, although these spaces were studied earlier by Karol Borsuk and others.

proved that dendroids have a fixed-point theorem: every continuous function from a dendroid to itself has a fixed point. proved that every dendroid is tree-like, meaning that it has arbitrarily fine open covers whose nerve is a tree. The question of whether more generally every tree-like continuum has a fixed-point theorem, posed by has been solved by David P. Bellamy

In Knaster's original publication on dendroids, in 1961, he posed the problem of characterizing the dendroids that can be embedded into the Euclidean plane, which also remains open. Another problem posed in the same year by Knaster, on the existence of an uncountable collection of dendroids with the property that no dendroid in the collection has a continuous surjection onto any other dendroid in the collection, was solved by and .

A locally connected dendroid is called a dendrite. A cone over the Cantor set (called a Cantor fan) is an example of a dendroid that is not a dendrite.

Dendroid is a Malware that affects Android OS and targets the mobile platform.

It was first discovered in early of 2014 by Symantec and appeared on the underground for sale for $300. Some things were noted in Dendroid, such as being able to hide from emulators at the time. When first discovered in 2014 it was one of the most sophisticated Android RATs known during that time It was one of the first Trojan applications to get past Google's Bouncer and caused researchers to warn about it being easier to create Android malware due to it It also seemed to follow in the footsteps of Zeus and SpyEye by having simple to use Command and control panels The code appeared to be leaked somewhere around 2014 It was noted that an apk binder was included in the leak which provided a simple way to bind dendroid to legitimate applications.
