Abstract Hermitian Algebras I. Spectral Resolution
David J. Foulis, Sylvia Pulmannova
We refer to the real Jordan Banach algebra of bounded Hermitian operators on a Hilbert space as a Hermitian algebra. We define an abstract Hermitian algebra (AH-algebra) to be the…

Sharp and fuzzy observables on effect algebras
A. Jencova, S. Pulmannova, E. Vincekova
Observables on effect algebras and their fuzzy versions obtained by means of confidence measures (Markov kernels) are studied. It is shown that, on effect algebras with the (E)-pro…

How sharp are PV measures?
A. Jencova, S. Pulmannova
Properties of sharp observables (normalized PV measures) in relation to smearing by a Markov kernel are studied. It is shown that for a sharp observable defined on a standard B…
