New Arcs of Maximal Size in Projective Hjelmslev Planes of Order Nine

Thomas Honold, Michael Kiermaier, Ivan Landjev


In this paper we solve two instances of the maximal arc problem for projective Hjelmslev planes of order 9.

Key words: arcs in projective Hjelmslev planes, finite chain rings, linear codes, projective Hjelmslev geometries
