Partially additive states on orthomodular posets
Josef Tkadlec · Colloquium Mathematicum · 1991
We fix a Boolean subalgebra B of an orthomodular poset P and study the mappings s:P → [0,1] which respect the ordering and the orthocomplementation in P and which are additive on B. We call such functions B-states on P. We first show that every P possesse
