A simple topological graph T = (V (T ), E(T )) is a drawing of a graph in the plane where every two edges have at most one common point (an endpoint or a crossing) and no three edges pass through a single crossing. Topological ...

(2013)
We introduce a class of solids that can be constructed gluing stackable pieces, which has been proven to have advantages in architectural construction. We derive a necessary condition for a solid to belong to this class. ...
