Revisiting the Applicability of Metaphysical Identity in Quantum Mechanics
Newton da Costa, Christian de Ronde
We discuss the hypothesis that the debate about the interpretation of the orthodox formalism of quantum mechanics (QM) might have been misguided right from the start by a biased me…
The Paraconsistent Logic of Quantum Superpositions
Newton da Costa, Christian de Ronde
Physical superpositions exist both in classical and in quantum physics. However, what is exactly meant by 'superposition' in each case is extremely different. In this paper we disc…
A formal framework for the study of the notion of undefined particle number in quantum mechanics
Newton da Costa, Federico Holik
It is usually stated that quantum mechanics presents problems with the identity of particles, the most radical position -supported by E. Schrodinger- asserting that elementary par…
On the Stability of Our Universe
Marcelo Samuel Berman, Newton C. A. da Costa
We argue that the Robertson-Walker's Universe is a zero-energy stable one, even though it may possess a rotational state besides expansion.
The Atiyah-Singer index theorem and the gauge field copy problem
Adonai S. Sant'Anna, Newton C. A. da Costa, Francisco A. Doria
K-theory allows us to define an analytical condition for the existence of `false' gauge field copies through the use of the Atiyah-Singer index theorem. After establishing that res…
