New Results on Arcs in Projective Hjelmslev Planes over Small Chain Rings
Thomas Honold, Michael Kiermaier, Ivan Landjev
We present various new constructions and bounds for arcs in projective Hjelmslev planes over finite chain rings of nilpotency index 2. For the chain rings of cardinality at most 25…
The degree of functions in the Johnson and q-Johnson schemes
Michael Kiermaier, Jonathan Mannaert, Alfred Wassermann
In 1982, Cameron and Liebler investigated certain "special sets of lines" in PG(3,q), and gave several equivalent characterizations. Due to their interesting geometric and algebrai…
Designs in finite classical polar spaces
Michael Kiermaier, Kai-Uwe Schmidt, Alfred Wassermann
Combinatorial designs have been studied for nearly 200 years. Fifty years ago, Cameron, Delsarte, and Ray-Chaudhury started investigating their q-analogs, also known as subspace de…
