Edge-decomposition into Two Triangular Forests is NP-complete

Beniamin Bibrowski, Tomáš Masařík

The paper proves that deciding whether a given graph can be edge‑decomposed into two triangular forests is NP‑complete.

Induced Erdős--Pósa property for long holes, long thetas, and beyond

Jadwiga Czyżewska, Tomáš Masařík, Marcin Pilipczuk +2

The induced Erdős--Pósa property in graphs relates the maximum number of pairwise anti-adjacent copies of an object with the minimum number of neighborhoods required to hit all c…

General Strong Bound on the Uncrossed Number via a Tight Bound for the Maximum Uncrossed Subgraph Number

Gaspard Charvy, Tomáš Masařík

We investigate a very recent concept for visualizing various aspects of a graph in the plane using a collection of drawings introduced by Hliněný and Masařík [GD 2023]. Formall…

Tree-independence number of -free graphs with no large bicliques

Václav Blažej, J. Pascal Gollin, Tomáš Hons +5

The tree-independence number of a graph is the minimum, over all tree-decompositions of the graph, of the maximum size of an independent set contained in a bag. Graph classes of bo…

Treewidth is Polynomial in Maximum Degree on Weakly Sparse Graphs Excluding a Planar Induced Minor

Édouard Bonnet, Jędrzej Hodor, Tuukka Korhonen +1

A graph contains a graph as an induced minor if can be obtained from after vertex deletions and edge contractions. We show that for every -vertex planar graph $H…
