Friction Theory and Structural Transformation of T_o: Normative Formation under the Entry of Non-Participating T_s

This paper examines the structural conditions under which the normative convergence state T_o(G), as defined in Friction Theory (Hideppa 2026a), is formed and transformed. Building on the analysis that AI outputs can be structurally described as T_s (Hideppa 2026b), this paper introduces the concept of T_sa (Actor-Absent T_s), referring to T_s whose generating subject does not belong to the target group G (A ∉ G). The paper proposes three propositions. 1. T_o(G) is a convergence state produced through friction among T_s within a target group G. 2. The friction structure differs depending on whether the generating subject belongs to G (A ∈ G) or not (A ∉ G). 3. AI-generated output (O_AI) constitutes a paradigm case of T_sa and can structurally reorganize T_o(G). The paper introduces two structural concepts: proxy friction and the T_o Undefined Domain. Together with two preceding papers, this work forms the third installment of the Friction Theory series describing the structural process from intra-subjective uniqueness (R_f) to social convergence (T_o).
