A new approach to representation of observables on fuzzy quantum posets

Le Ba Long
1992 Applications of Mathematics  
It is obvious that a fuzzy quantum space is a fuzzy quantum poset, and a model I of a fuzzy quantum poset is a model II, but the converse is not true, in general, as we can see below. Example 1.  ...  Let (Q, M) be a model I or II of fuzzy quantum posets. Let a be a given fuzzy set of M.  ...

Thus any quantum poset is also a fuzzy quantum poset. There also ex- ist fuzzy quantum posets that are essentially fuzzy (i.e., for some of their propositions the truth value is from (0,1)).  ...  A definition of a fuzzy quantum poset [Lé ba Long, Acta Math. Univ.  ...

The basic notions of the quantum logic theory -a state and an observable are defined in D-posets of fuzzy sets.  ...  The new algebraic structure of fuzzy sets is called a difference poset (a D-poset) of fuzzy sets. Some properties of a lattice ordered D-poset of fuzzy sets (a D-lattice of fuzzy sets) are studied.  ...  Then F is a fuzzy-q-σ-algebra and ( X , F) is an F-quantum poset. F-quantum spaces and F-quantum posets were studied by many authors.  ...

The main ideas are that quantum mechanics is a mechanics whose underlying logic is a fuzzy logic, and classical mechanics is a crisp limit of quantum mechanics based on fuzzy logic.  ...  Another topic of the paper is quantum computing and its con- nection with quantum mechanics and fuzzy logic.  ...

An example of a quasi-orthocomplemented poset that is not a g-orthocomplemented poset is an F-quantum poset {[A. Dvuretenskij and F. Chovanec, Internat. J. Theoret.  ...  A quasi-orthocomplemented poset P is a generalization of a o- orthocomplemented poset.  ...

Further, extending the funda- mental notions of quantum logics theory, they define observables and states on D-o-posets as D-o-poset-structure-preserving map- pings respectively from the o-algebra @(R)  ...  He proves that every such h-fuzzy quantum logic is actually a quantum logic, and provides some reasonable arguments in favor of his hypothesis that another choice of operations will not lead to a quantum  ...

Among utilized models, we can find orthomodular lattices (quantum logics), difference posets (effect algebras), multivalue algebras and fuzzy sets.  ...  In the first paper ''Conditional states and independence in D-posets'' by authors Chovanec Ferdinand, Drobná Eva, Kôpka František and Nánásiová Olga (Slovakia) conditional states on difference posets are  ...

Geometric viewpoint on the quantization of a fuzzy logic [article]

2020 arXiv   pre-print
Considering the geometric formulation of quantum mechanics we give a description of quantum propositions in terms of fuzzy events in a complex projective space equipped with Kähler structure (the quantum  ...  phase space) obtaining a quantized version of a fuzzy logic by deformation of the product t-norm.  ...  from a class of fuzzy sets such that the compatibility in the poset is related to the commutation w.r.t. ⋆.  ...

Fuzzification of probabilistic objects

Martin Papco
2013 Proceedings of the 8th conference of the European Society for Fuzzy Logic and Technology  
Using our previous results, we show that the category ID of D-posets of fuzzy sets provides a framework in which the transition from classical to fuzzy probability theory is the consequence of some natural  ...  We introduce two categories CP and FP of probability spaces and observables corresponding to the classical probability theory and the fuzzy probability theory, respectively.  ...  Such observables correspond to genuine fuzzy (operational) random variables and have definite quantum qualities.  ...
