An axiom system for full 3 -dimensional Euclidean geometry

Jarosław Kosiorek (1991)

Mathematica Bohemica

Similarity:

We present an axiom system for class of full Euclidean spaces (i.e. of projective closures of Euclidean spaces) and prove the representation theorem for our system, using connections between Euclidean spaces and elliptic planes.

On the convex hull of projective planes

Jean-François Maurras, Roumen Nedev (2008)

RAIRO - Operations Research

Similarity:

We study the finite projective planes with linear programming models. We give a complete description of the convex hull of the finite projective planes of order . We give some integer linear programming models whose solution are, either a finite projective (or affine) plane of order , or a -arc.
