Combinatorics and algorithms for quasi-chain graphs
Bogdan Alecu, Aistis Atminas, Vadim Lozin +1
The class of quasi-chain graphs is an extension of the well-studied class of chain graphs. This latter class enjoys many nice and important properties, such as bounded clique-width…
Graph classes with linear Ramsey numbers
Bogdan Alecu, Aistis Atminas, Vadim Lozin +1
The Ramsey number for a class of graphs is the minimum such that every graph in with at least vertices has either a clique of size or an independent…
Graph functionality
Bogdan Alecu, Aistis Atminas, Vadim Lozin
Let be a graph and its adjacency matrix. We say that a vertex is a function of vertices if there exists a Boolean function of $…
Classes of graphs without star forests and related graphs
Aistis Atminas
This work provides a structural characterisation of hereditary graph classes that do not contain a star forest, several graphs obtained from star forests by subset complementation,…
On forbidden induced subgraphs for unit disk graphs
Aistis Atminas, Viktor Zamaraev
A unit disk graph is the intersection graph of disks of equal radii in the plane. The class of unit disk graphs is hereditary, and therefore admits a characterization in terms of m…
