Abstract in another language
We complete the determination of the maximum sizes of (k,n)-arcs, n ≤ 12, in the projective Hjelmslev planes over the two (proper) chain rings ℤ₉=ℤ/9ℤ and S₃=F₃[X]/(X²) of order 9 by resolving the hitherto open cases n=6 and n=7. Part of our proofs rely on decidedly geometric properties of the planes such as Desargues’ Theorem and the existence of certain subplanes.
