Tomaž Pisanski: Splittable and unsplittable graphs and configurations

Povzetek. We prove that there exists infinitely many splittable and also infinitely many unsplittable 3-configurations. We also present a study of small trivalent cyclic Haar graphs with respect to splittability.

This is work in progress with Nino Bašić, Jan Grošelj, Branko Grünbaum and Jaka Kranjc.
