On the Circuit Diameter of some Combinatorial Polytopes
Sean Kafer, Kanstantsin Pashkovich, Laura Sanità
The combinatorial diameter of a polytope is the maximum value of a shortest path between two vertices of , where the path uses the edges of only. In contrast to the comb…
The geometry of hyperbolic lines in polar spaces
Hans Cuypers
In this paper we consider partial linear spaces induced on the point set of a polar space, but with as lines the hyperbolic lines of this polar space. We give some geometric charac…
On some subgroups of linear groups over generated by elements of order
Hans Cuypers
Let be a vector space over the field of order . We investigate subgroups of the linear group which are generated by a conjugacy class of elements of order su…
A geometric characterization of the classical Lie algebras
Hans Cuypers, Yael Fleischmann
A nonzero element x in a Lie algebra g over a field F with Lie product [ , ] is called a extremal element if [x, [x, g]] is contained in Fx. Long root elements in classical Lie alg…
Firefighting on trees and Cayley graphs
Florian Lehner
We study Hartnell's firefighter problem on infinite trees and characterise the branching number in terms of the firefighting game. Using our results about trees, we give a partial…
Binomial collisions and near collisions
Aart Blokhuis, Andries Brouwer, Benne de Weger
We describe efficient algorithms to search for cases in which binomial coefficients are equal or almost equal, give a conjecturally complete list of all cases where two binomial co…
