Physics of Difference II: Comparison Structure and the Emergence of Topology
Yasuaki Tamura
AbstractWe investigate the minimal structural conditions under which relational accessibility organization admits a topological representation within physical description. Starting solely from the existence of distinguishable states and admissible comparison relations, we analyze how accessibility structures arise without introducing prior notions of space, geometry, metric structure, probability, or dynamics.Within the present framework, comparison between states is interpreted as a structural relation governing the accessibility of distinctions. The consistency requirements imposed on admissible comparisons induce preorder-like relational organization on the state space. We show that such comparison-induced accessibility structures admit neighborhood-like representations and may be organized in a form compatible with topological description.Importantly, the present framework does not interpret topology as a primitive geometric entity. Rather, topological structure is treated as a mathematical representation of relational accessibility induced by admissible comparison structure. In this perspective, neighborhood relations characterize accessibility coherence among distinguishable states rather than spatial proximity in a preexisting geometric manifold.We further show that equivalence structures associated with comparison naturally introduce classes of states that are indistinguishable within a given accessibility framework while remaining structurally distinct in the underlying state space. This provides a relational interpretation of local accessibility organization without invoking observer-dependent notions or externally imposed representational scales.The present work does not introduce new mathematical constructions. Instead, it identifies structural conditions under which topological representation becomes compatible with a minimal relational framework of physical description.
