2. Uniform binary geometries

   In a geometric lattice every interval can be mapped isomorphically into an upper interval (containing 1) by a strong map. A natural question thus...

5. Existence of parallelisms and projective extensions for strongly n-uniform near affine Hjelmslev planes

   An affine Hjelmslev plane is a near affine Hjelmslev plane with a parallelism. It is proved that every strongly n -uniform near affine Hjelmslev plane...

6. Subgroups of binary relations

   A binary relation defined on a set containing n elements can be interpreted as an n × n incidence matrix. Such matrix may be taken either over the...
