Set theoretical model for magnetism

Exploring the intersection of magnetism and set theory, this work delves into dimension problems, specifically within the Heisenberg and Ising models. It presents a proof regarding the cardinality of magnetic domains and employs fixed Brouwer theory to analyze their motion. The author proposes a unified theoretical model for magnetism and applies the mathematics of belief revision to develop a framework for understanding ferro-para phenomena. This intricate study bridges complex concepts in physics and mathematics.
