We study a new family of geometric graphs that interpolate between the Delaunay triangulation and the Gabriel graph. These graphs share many properties with skeletons for [0, 1]...

We investigate the relationship between geometric thickness and the thickness, outerthickness, and arboricity of graphs. In particular, we prove that all graphs with arboricity tw...

We consider restoring the bilateral symmetry of an object which has been deformed by compression. This problem arises in paleontology, where symmetric bones are compressed in the ...
