N-free posets and orthomodularity
Gejza Jenča
We prove that the incomparability orthoset of a finite poset is Dacey if and only if the poset is N-free. We give a characterization of finite posets with compatible incomparabilit…

Quantum Suplattices
Gejza Jenča, Bert Lindenhovius
Building on the theory of quantum posets, we introduce a non-commutative version of suplattices, i.e., complete lattices whose morphisms are supremum-preserving maps, which form a…
