Can quantum particles be regarded as individuals, just like books, tables and people?
According to the'received'view-articulated by several physicists in the immediate aftermath of …

Our aim in this paper is to take quite seriously Heinz Post's claim that the non-individuality
and the indiscernibility of quantum objects should be introduced right at the start, and not …

In this paper, we examined the connection between quantum systems' indistinguishability
and signed (or negative) probabilities. We do so by first introducing a measure-theoretic …

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 …

The 'ontic'form of structural realism (OSR), roughly speaking, admits a complete elimination
of the objects in the discourse of scientific theories, leaving us with structures only. As put by …

Georg Cantor said that a set is a collection into a whole of defined and distinct objects. This
intuitive idea is in certain sense grasped by standard set theories, like Zermelo-Fraenkel's …

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 …

Quasi-set theory was developed to deal with collections of indistinguishable objects. In
standard mathematics, there are no such kind of entities, for indistinguishability (agreement …

Neste artigo discutimos algumas questões propostas por Newton da Costa relacionadas
aos fundamentos da teoria de quase-conjuntos. Seus questionamentos aqui considerados …

Quasi-set theory 𝔔 is a first order theory which allows us to cope with certain collections of
objects where the usual notion of identity is not applicable, in the sense that x= x is not a …
