• Aspectos lógicos y algebraicos de la Mecánica cuántica
    Facultad de Filosofía y Letras, Universidad de Buenos Aires. 2026.
    El análisis de los vínculos que pueden ser establecidos entre la lógica cuántica, las semánticas no deterministas de Nmatrices y las teorías de cuasiconjuntos es el núcleo central de este trabajo. La necesidad de tal análisis ha surgido de forma natural luego de que la relación entre Nmatrices y lógica cuántica quedó explicitada en un trabajo previo: los estados cuánticos, entendidos como medida de probabilidad, pueden ser interpretados como valuaciones de una cierta Nmatriz para el retículo cuá…Read more
  • Animalidad, otredad e inmortalidad en "El inmortal"
    Logos: Revista de Lingüística, Filosofía y Literatura 35 (1). 2025.
    En el presente trabajo, analizamos el cuento El Inmortal de Borges prestándole principal atención a las situaciones donde se entrelazan, o se tratan sin diferenciar demasiado, cuestiones vinculadas con la animalidad y la divinidad. Sostenemos que esta especie de confusión o falta de precisión al tratar cuestiones que se alejan tanto de la identidad personal y del Yo, como la inmortalidad, no es un elemento casual ni sin fundamento, sino que puede ser analizado filosóficamente adentrándonos la ot…Read more
  • In this paper, we introduce a quasi-set theory without atoms. The quasi-sets (qsets) can have as elements completely indiscernible things which do not turn out to be the very same thing as it would be implied if its underlying logic was classical logic. A quasi-set can have a cardinal, called its quasi-cardinal, but this is made so that, at least for the finite case, the quasi-cardinal is not an ordinal, and hence the indistinguishable elements of a quasi-set cannot be ordered. In the last secti…Read more
  • COMPLEXITY VALUATIONS: A GENERAL SEMANTIC FRAMEWORK FOR PROPOSITIONAL LANGUAGES
    Juan Pablo Jorge, Hernán Luis Vázquez, and Federico Holik
    Actas Del Xvii Congreso Dr. Antonio Monteiro. forthcoming.
    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 potent…Read more
  • 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.
  • We discuss a reconstruction of standard quantum mechanics assuming indistinguishability right from the start, by appealing to quasi-set theory. After recalling the fundamental aspects of the construction and introducing some improvements in the original formulation, we extract some conclusions for the interpretation of quantum theory.

  • We analyze the contributions that quasi-set theories can make to the interests of logic. Different quasi-set theories have made valuable contributions to the foundations of mathematics and quantum physics; however, it is not clear how much such formalisms can benefit logic. If so, could they have repercussions at both the syntactic and semantic levels? What precautions should we take? What implications would their application have at different levels and metalevels of logical language? Motivated…Read more
  • Relating quasi-sets and rough sets: from quantum entities to AI
    International Journal of Theoretical Physics 64 (289). 2025.
    At present, there are at least two set theories motivated by quantum ontology: Décio Krause’s quasi-set theory (Q) and Maria Dalla Chiara and Giuliano Toraldo di Francia’s quasi-set theory (QST). Recent work [Jorge-Holik-Krause, 2023] has established certain links between QST and Pawlak’s rough set theory (RST), showing that both are strong candidates for providing a non-deterministic semantics of N matrices that generalizes those based on ZF. In this work, we show that the new atomless quas…Read more
  • One of the main ontological challenges posed by quantum mechanics is the problem of the indistinguishability of so-called “identical” particles, that is, particles that share the same state-independent properties. In the framework of this philosophical problem, a quasi-set theory was formulated to provide a proper metalanguage to deal with quantum indistinguishability; this theory included certain Urelemente called m-atoms, representing essentially indistinguishable objects. In turn, over the …Read more
  • Nmatrices cuánticas, cuasiconjuntos y el teorema de Kochen-Specker
    Teorema: International Journal of Philosophy 44 (2): 1-28. 2025.
    We analyze two fundamental premises of the Kochen-Specker theorem: a) the functionality condition FUNC, which expresses the fact that not all observables are independent, nor are the values assigned to them, and b) the issue of the identity of projectors in different measurement contexts. We show that the non-deterministic semantics of Nmatrices and the theory of qsets Q− can complement each other by providing an appropriate semantics for the lattice of quantum projectors. Considering valuations…Read more
