结构九章 Jiuzhang of Structure 偏–合–调–均 A Structural Reconstruction of Harmonization Mathematics

Jiuzhang Suanshu is not just a mathematical classic; it is a pre-modern system of structural reasoning. In this book, we reconstruct the Nine Chapters as nine structural collapse models, each governed by a four-stage harmonization logic: Residual (偏piān), Aggregation (合hé), Local Harmonization (调tiáo), and Global Collapse Convergence (均 jūn). In this context, ”collapse” refers to a structural-informational convergence, not a physical collapse.
