Heap - ternary algebraic structure
Z. Kolar
Abstract
In this paper some classes of ternary algebraic structures (semi-heaps, heaps) are considered. The connection between heaps (laterally commutative heaps) and corresponding algebraic
and geometric structures is presented.
The equivalence of heap existence and the Desargues system on the same set is directly proved. It is the starting point for an analogous
result about a laterally commutative heap and a parallelogram space.
