Paper IUT-C — Communicating Without Mixing

This release publishes the IUT-C series (v1.00), including the core paper, six appendices, and six structural figures in both Japanese and English. Paper IUT-C — Communicating Without Mixing provides a structural interpretation of a design principle suggested by Inter-Universal Teichmüller Theory (IUT): that distinct frameworks may correspond without being merged. The paper reformulates this principle as an operational model within Dualbind, where heterogeneous systems—mathematical, physical, linguistic, or AI-based—are treated as structurally separated domains connected through controlled correspondence rather than fusion. The appendices function as formal specifications and boundary definitions. They fix terminology (GLS), define boundary and authority conditions (BND), clarify the scope of the C-layer Statistical Response Generation Model (SRE), document dialogue-based design decisions (DLG), provide comparative mappings (CMP), and document physical homology as a structural analogy (PHS). The figures visualize the communication structure and layer separations described in the text. This series does not claim any new mathematical or physical discoveries. Instead, it proposes a structural interpretative and operational framework for managing non-equivalent domains without collapsing them into a unified system. Structural and interdisciplinary feedback is welcome. For correspondence: [email protected]: CC BY 4.0
