Clique-Width of Point Configurations,y. As a case study we propose a natural extension of the structural graph parameter of . to geometric point configurations represented by their .. We study basic properties of this clique-width notion, and relate it to the monadic second-order logic of point configurations. As an application, we pro

Treewidth Versus Clique Number in Graph Classes with a Forbidden Structure,ed treewidth is the absence of large cliques. We study graph classes in which this condition is also sufficient, which we call .-bounded. Such graph classes are known to have useful algorithmic applications related to variants of the clique and .-coloring problems. We consider six well-known graph c

Plattenbauten: Touching Rectangles in Space,uching graphs of axis-aligned rectangles in?.. We prove that planar 3-colorable graphs can be represented as touching graphs of axis-aligned rectangles in?.. The result implies a characterization of corner polytopes previously obtained by Eppstein and Mumford. A by-product of our proof is a distribu
