Geometric intersection graphs form an intriguing class of structures in which vertices represent geometric objects – such as line segments, discs, or curves – and an edge is established between two ...

Abstract We calculate the intersection ring of 3-dimensional graph manifolds with rational coefficients and give an algebraic characterization of these rings when the manifold’s underlying graph is a ...

Conflict-free colouring represents a rapidly evolving area of combinatorial optimisation with significant implications for both theoretical research and practical applications. In this framework, ...
