Basic Notions and Properties of Orthoposets

Markus Moschner

Saarland University

This paper was worked out while the author was visiting the
University of Bia{\l}ystok in autumn 2002.
Summary.

Orthoposets are defined.
The approach is the standard one via order relation similar
to common text books on algebra like [9].
This work has been partially supported by the CALCULEMUS project
(FP5 grant HPRNCT200000102).
