Atomic Sequential Effect Algebras
(2008)
Various conditions ensuring that a sequential effect algebra or the set of sharp
elements of a sequential effect algebra is a Boolean algebra are presented.
Concrete Quantum Logics with Generalised Compatibiliy
(1998)
We present three results stating when a concrete (= set-representable) quantum
logic with covering properties (generalization of compatibility) has to be a Boolean algebra.
These results complete and generalize some ...
