Abstract: The 6-property for 2-dimensional simplicial complexes is the condition that every nontrivial circuit in the link of a vertex has length greater than or equal to six. If a compact -manifold
has a 2-dimensional spine with the 6-property, then we show that the interior of
is covered by euclidean
-space. In dimension
, we show further that such a 3-manifold is Haken.
