A universal algebra approach to free projective planes.
A universal algebra approach to free projective planes. (Short Communication).
Affine line systems in finite-dimensional vector spaces.
Almost hermitian geometry on six dimensional nilmanifolds
An axiom system for full -dimensional Euclidean geometry
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.
