Arnold's Projective Plane and ð ‘Ÿ -Matrices

Advances in Mathematical Physics, 2010, vol. 2010, 1-9

Abstract:

We will explain Arnold's 2-dimensional (shortly, 2D) projective geometry (Arnold, 2005) by means of lattice theory. It will be shown that the projection of the set of nontrivial triangular ð ‘Ÿ -matrices is the pencil of tangent lines of a quadratic curve on Arnold's projective plane.
