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.

Homography in ℝℙ

Roland Coghetto (2016)

Formalized Mathematics

Similarity:

The real projective plane has been formalized in Isabelle/HOL by Timothy Makarios [13] and in Coq by Nicolas Magaud, Julien Narboux and Pascal Schreck [12]. Some definitions on the real projective spaces were introduced early in the Mizar Mathematical Library by Wojciech Leonczuk [9], Krzysztof Prazmowski [10] and by Wojciech Skaba [18]. In this article, we check with the Mizar system [4], some properties on the determinants and the Grassmann-Plücker relation in rank 3 [2], [1], [7],...
