| Abstract: | The Dembowski semi-planes are the semi-planes which were determined by P. Dembowski 3]. A Dembowski semi-i-space (i 1) is an incidence structure J=(P,B,I) for which: (i) each element of B is incident with at least i+3 elements of P, and (ii) each i-residual space of J is a Dembowski semi-plane. The article 5] contained the complete classification of all Dembowski semi-1-spaces, in this article we classify all Dembowski semi-2-spaces. |
