  1. Quasi-set theory: a formal approach to a quantum ontology of properties.Federico Holik, Juan Pablo Jorge, Décio Krause & Olimpia Lombardi - 2022 - Synthese 200 (5):1-26.
    In previous works, an ontology of properties for quantum mechanics has been proposed, according to which quantum systems are bundles of properties with no principle of individuality. The aim of the present article is to show that, since quasi-set theory is particularly suited for dealing with aggregates of items that do not belong to the traditional category of individual, it supplies an adequate meta-language to speak of the proposed ontology of properties and its structure.

  2. On the Connection Between Quantum Probability and Geometry.Federico Holik - 2021 - Quanta 10 (1):1-14.
    We discuss the mathematical structures that underlie quantum probabilities. More specifically, we explore possible connections between logic, geometry and probability theory. We propose an interpretation that generalizes the method developed by R. T. Cox to the quantum logical approach to physical theories. We stress the relevance of developing a geometrical interpretation of quantum mechanics.

  3. Open Problems in the Development of a Quantum Mereology.Federico Holik & Juan Pablo Jorge - 2023 - In Jonas R. B. Arenhart & Raoni W. Arroyo (eds.), Non-Reflexive Logics, Non-Individuals, and the Philosophy of Quantum Mechanics: Essays in Honour of the Philosophy of Décio Krause. Springer Verlag. pp. 157-176.
    Mereology deals with the study of the relations between wholes and parts. In this work we will discuss different developments and open problems related to the formulation of a quantum mereology. In particular, we will discuss different advances in the development of formal systems aimed to describe the whole-parts relationship in the context of quantum theory.

  4. A discussion on the origin of quantum probabilities.Federico Holik, Manuel Sáenz & Angelo Plastino - 2014 - Annals of Physics 340 (1):293-310.
    We study the origin of quantum probabilities as arising from non-Boolean propositional-operational structures. We apply the method developed by Cox to non distributive lattices and develop an alternative formulation of non-Kolmogorovian probability measures for quantum mechanics. By generalizing the method presented in previous works, we outline a general framework for the deduction of probabilities in general propositional structures represented by lattices (including the non-distributive case).

  5. Non-Kolmogorovian Probabilities and Quantum Technologies.Federico Holik - 2023 - Entropy 24 (11):1666.
    In this work, we focus on the philosophical aspects and technical challenges that underlie the axiomatization of the non-Kolmogorovian probability framework, in connection with the problem of quantum contextuality. This fundamental feature of quantum theory has received a lot of attention recently, given that it might be connected to the speed-up of quantum computers—a phenomenon that is not fully understood. Although this problem has been extensively studied in the physics community, there are still many philosophical questions that should be properly (...)

    Apesar de ter florescido no século XII, a tradição do Graal, remonta ao século VI, com a história da “Destruição e Conquista da Bretanha”, escrita pelo clérigo Gildas, que não parece querer retratar mais do que fatos da época envolvendo líderes locais com status de Rei, lutas pelo poder, batalhas e assassinatos em família, todavia, se alguma tradição subterrânea (prática comum entre os judeus) havia, envolvendo esses personagens, sobre isso, Gildas, nada falou. -/- A memória desses homens guerreiros volta à (...)

  8. Contextuality and Indistinguishability.Acacio de Barros, Federico Holik & Décio Krause - 2017 - Entropy 19 ((9)):435.
    It is well known that in quantum mechanics we cannot always define consistently properties that are context independent. Many approaches exist to describe contextual properties, such as Contextuality by Default, sheaf theory, topos theory, and non-standard or signed probabilities. In this paper we propose a treatment of contextual properties that is specific to quantum mechanics, as it relies on the relationship between contextuality and indistinguishability. In particular, we propose that if we assume the ontological thesis that quantum particles or properties (...)

  9. Indistinguishability and the origins of contextuality in physics.José Acacio De Barros, Federico Holik & Décio Krause - 2019 - Philosophical Transactions of the Royal Society A 377 (2157): 20190150.
    In this work, we discuss a formal way of dealing with the properties of contextual systems. Our approach is to assume that properties describing the same physical quantity, but belonging to different measurement contexts, are indistinguishable in a strong sense. To construct the formal theoretical structure, we develop a description using quasi-set theory, which is a set-theoretical framework built to describe collections of elements that violate Leibnitz's principle of identity of indiscernibles. This framework allows us to consider a new ontology (...)

  10. O elo entre o passado esquecido e o passado desconhecido.Frederico Rochaferreira - unknown
    A grande maioria das pessoas pouco ou nada sabe sobre o fenício Sanchuniathon e seus registros históricos acerca do pré-sumeriano Taautus, o homem que nos transmitiu a escrita. O que chegou até nós, chegou por graça e obra de Eusébio de Cesaréia, que utilizou partes de seus escritos para refutá-lo, como no livro, “Praeparatio evangelica". Tudo começa com Filo de Biblos, um erudito também fenício, que ao tomar conhecimento da monumental obra de seu compatriota, tratou de traduzi-la para o grego, (...)

  11. Reflexão sobre o vazio intelectual na sociedade brasileira provocado pelo sistema de ensino.Frederico Rochaferreira - 2022 - ResearchGate.
    Educação de qualidade é o alicerce que sustenta todas as construções sociais avançadas, porque é a promotora do desenvolvimento social, cultural, científico, tecnológico e moral. A escola, portanto, é o útero gerador da civilização civilizada e quando ela não cumpre esse papel, inexoravelmente coloca o homem à margem de sua sociedade e a sociedade a que pertence à margem do desenvolvimento global. Este esboço reflete a preocupação com os caminhos da educação no Brasil, a priori, o método estéril de ensinar (...)

    Non-Deterministic Semantics for Quantum States.Juan Pablo Jorge & Federico Holik - 2020 - Entropy 22 (2):156.
    In this work, we discuss the failure of the principle of truth functionality in the quantum formalism. By exploiting this failure, we import the formalism of N-matrix theory and non-deterministic semantics to the foundations of quantum mechanics. This is done by describing quantum states as particular valuations associated with infinite non-deterministic truth tables. This allows us to introduce a natural interpretation of quantum states in terms of a non-deterministic semantics. We also provide a similar construction for arbitrary probabilistic theories based (...)

    An Algebraic Model for Quantum Unstable States.Sebastian Fortin, Manuel Gadella, Federico Holik, Juan Pablo Jorge & Marcelo Losada - 2022 - Mathematics 10 (23).
    In this review, we present a rigorous construction of an algebraic method for quantum unstable states, also called Gamow states. A traditional picture associates these states to vectors states called Gamow vectors. However, this has some difficulties. In particular, there is no consistent definition of mean values of observables on Gamow vectors. In this work, we present Gamow states as functionals on algebras in a consistent way. We show that Gamow states are not pure states, in spite of their representation (...)

    Lógica cuántica, Nmatrices y adecuación, II.Juan Pablo Jorge & Federico Holik - 2023 - Teorema: International Journal of Philosophy 42 (1):149-169.
    By elaborating on the results presented in Lógica cuántica, Nmatrices y adecuación I, here we discuss the notions of adequacy and truth functionality in quantum logic from the point of view of a non-deterministic semantics based on Nmatrices. We present a proof of the impossibility of providing a functional semantics for the quantum lattice. An advantage of our proof is that it is independent of the number of truth values involved, generalizing previous works. Due to the impossibility of defining adequate (...)

    In this paper we discuss the notions of adequacy and truth functionality in quantum logic from the point of view of a non-deterministic semantics. We give a characterization of the degree of non-functionality which is compatible with the propositional structure of quantum theory, showing that having truth-functional connectives, together with some assumptions regarding the relation of logical consequence, commits us to the adequacy of the interpretation sets of these connectives. An advantage of our proof is that it is independent of (...)

  17. An Approach to QST-based Nmatrices Semantics.Juan Pablo Jorge, Federico Holik & Décio Krause - 2023 - Principia: An International Journal of Epistemology 27 (3):539-607.
    This paper introduces the theory QST of quasets as a formal basis for the Nmatrices. The main aim is to construct a system of Nmatrices by substituting standard sets by quasets. Since QST is a conservative extension of ZFA (the Zermelo-Fraenkel set theory with Atoms), it is possible to obtain generalized Nmatrices (Q-Nmatrices). Since the original formulation of QST is not completely adequate for the developments we advance here, some possible amendments to the theory are also considered. One of the (...)

    COMPLEXITY VALUATIONS: A GENERAL SEMANTIC FRAMEWORK FOR PROPOSITIONAL LANGUAGES.Juan Pablo Jorge, Hernán Luis Vázquez & Federico Holik - forthcoming - Actas Del Xvii Congreso Dr. Antonio Monteiro.
    A general mathematical framework, based on countable partitions of Natural Numbers [1], is presented, that allows to provide a Semantics to propositional languages. It has the particularity of allowing both the valuations and the interpretation Sets for the connectives to discriminate complexity of the formulas. This allows different adequacy criteria to be used to assess formulas associated with the same connective, but that differ in their complexity. The presented method can be adapted potentially infinite number of connectives and truth values, (...)

    On the assumptions underlying KS-like contradictions.José Acacio de Barros, Juan Pablo Jorge & Federico Holik - manuscript
    The Kochen-Specker theorem is one of the fundamental no-go theorems in quantum theory. It has far-reaching consequences for all attempts trying to give an interpretation of the quantum formalism. In this work, we examine the hypotheses that, at the ontological level, lead to the Kochen-Specker contradiction. We emphasize the role of the assumptions about identity and distinguishability of quantum objects in the argument.

    O homem no decorrer de sua evolução social sempre pôs a natureza como um objeto e dificilmente pensou ela como sendo parte de um complexo sistema influenciável pelos fatores humanos. Apesar da atualidade desse debate, a constituição brasileira de 1988 apresenta em diversas normas, a proteção do meio ambiente e a defesa do desenvolvimento sustentável como valor constitucional. Porém, desde a materialização desses princípios, pode-se perceber que as concepções defendidas não estão sendo defendidas ou interpretadas de acordo com o que (...)

  23. TORC3: Token-Ring Clearing Heuristic for Currency Circulation.Julio Michael Stern, Carlos Humes, Marcelo de Souza Lauretto, Fabio Nakano, Carlos Alberto de Braganca Pereira & Guilherme Frederico Gazineu Rafare - 2012 - AIP Conference Proceedings 1490:179-188.
    Clearing algorithms are at the core of modern payment systems, facilitating the settling of multilateral credit messages with (near) minimum transfers of currency. Traditional clearing procedures use batch processing based on MILP - mixed-integer linear programming algorithms. The MILP approach demands intensive computational resources; moreover, it is also vulnerable to operational risks generated by possible defaults during the inter-batch period. This paper presents TORC3 - the Token-Ring Clearing Algorithm for Currency Circulation. In contrast to the MILP approach, TORC3 is a (...)
