On the Weisfeiler-Leman dimension of some polyhedral graphs

Haiyan Li, Ilia Ponomarenko, Peter Zeman

Let be a positive integer, a graph with vertex set , and the coloring of the Cartesian -power , obtained by the -dimensional Weisfeiler-Leman…

Beyond circular-arc graphs -- recognizing lollipop graphs and medusa graphs

Deniz Ağaoğlu Çağırıcı, Onur Çağırıcı, Jan Derbisz +5

In 1992 Biró, Hujter and Tuza introduced, for every fixed connected graph , the class of -graphs, defined as the intersection graphs of connected subgraphs of some subdivisio…

Recognition and Isomorphism of Proper -graphs in FPT-time

Deniz Ağaoğlu Çağırıcı, Peter Zeman

An -graph is an intersection graph of connected subgraphs of a suitable subdivision of a fixed graph . Many important classes of graphs, including interval graphs, circular-a…

Extending Partial Representations of Circular-Arc Graphs

Jiří Fiala, Ignaz Rutter, Peter Stumpf +1

The partial representation extension problem generalizes the recognition problem for classes of graphs defined in terms of vertex representations. We exhibit circular-arc graphs as…

Testing isomorphism of chordal graphs of bounded leafage is fixed-parameter tractable

Vikraman Arvind, Roman Nedela, Ilia Ponomarenko +1

The computational complexity of the graph isomorphism problem is considered to be a major open problem in theoretical computer science. It is known that testing isomorphism of chor…

Automorphism groups of maps in linear time

Ken-ichi Kawarabayashi, Bojan Mohar, Roman Nedela +1

By a map we mean a -cell decomposition of a closed compact surface, i.e., an embedding of a graph such that every face is homeomorphic to an open disc. Automorphism of a map can…
