Hilbert fragments

Csaba Biró, André E. Kézdy, Jen\Ho Lehel

In earlier work, we proved that the length polyhedron of an interval order has a unique Hilbert basis and that every element of this basis is a binary vector. The supports of these…

Infinite graphs with finite metric dimension

Csaba Biró, Caroline E. Boone, Beth Novick +1

We study the metric dimension (strong and weak) of infinite graphs. In particular, our main interest is characterizing infinite graphs with finite dimension. Our main results: (1)…

Semiorders induced by uniform random points

Csaba Biró, Caroline E. Boone

We study semiorders induced by points drawn from a uniform random distribution. Of particular interest in this paper are the probabilities of generating specific semiorders and the…

Two-count interval representation of a permutation

Csaba Biró, André E. Kézdy, Jenő Lehel

The interval count problem, a classical question in the study of interval orders, was introduced by Ronald Graham in the 1980s. This problem asks: given an interval order , what…

The length polyhedron of an interval order

Csaba Biró, André E. Kézdy, Jenő Lehel

The length polyhedron of an interval order is the convex hull of integral vectors representing the interval lengths in interval representations of . This polyhedron ha…

Packing independent cliques into planar graphs

Csaba Biró, Gabriel Collado, Oscar Zamora

The indeque number of a graph is largest set of vertices that induce an independent set of cliques. We study the extremal value of this parameter for the class and subclasses of pl…
