In the present paper we use such a formalism as a model for quasi-set theory. Quasi-set theory, based on Zermelo-Fraenkel set theory, was developed for dealing with collections of indistinguishable but, in a sense, not identical objects.LaTeX, 14 pages, no figures, one tableQuantum PhysicsHidden variables, quasi-sets, and elementary particlestext
