Dendroid (topology)

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 Bronislaw Knaster lecturing at the University of Wroclaw, although these spaces were studied earlier by Karol Borsuk and others.
