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 ...

At the International Workshop on Combinatorial Image Analysis, held in Brno, Czech Republic, our URGE To Compute team received the Best Student Paper Award for their presentation, "On Intersection ...

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

A function is a rule that is applied to one set of values to give another set of values. A function can be illustrated on a graph – points are plotted as coordinates and joined by either a straight ...
