Separable Drawings: Extendability and Crossing-Free Hamiltonian Cycles
Oswin Aichholzer, Joachim Orthaber, Birgit Vogtenhuber
Generalizing pseudospherical drawings, we introduce a new class of simple drawings, which we call separable drawings. In a separable drawing, every edge can be closed to a simple c…
Holes in Convex and Simple Drawings
Helena Bergold, Joachim Orthaber, Manfred Scheucher +1
Gons and holes in point sets have been extensively studied in the literature. For simple drawings of the complete graph a generalization of the Erdős--Szekeres theorem is known and…
Plane Hamiltonian Cycles in Convex Drawings
Helena Bergold, Stefan Felsner, Meghana M. Reddy +2
A conjecture by Rafla from 1988 asserts that every simple drawing of the complete graph admits a plane Hamiltonian cycle. It turned out that already the existence of much sim…
