Homeostatic Regulation⤓ .md 2026-07-13T092753.000 000000000012768 Pyotr Anokhin's theory of functional systems (1930s-1970s); Ashby's cybernetic adaptation mechanisms imported into Soviet physiology and engineering.
Lyapunov Stability⤓ .md 2026-07-13T092753.000 000000000012184 Aleksandr Lyapunov's doctoral thesis (1892); foundational to Soviet control theory; extended by Lur'e, Yakubovich, and the absolute stability school.
Optimal Control Decomposition⤓ .md 2026-07-13T092753.000 000000000014912 Lev Pontryagin's maximum principle (1956); applied to economic planning via Kantorovich and Nemchinov; hierarchical decomposition via Mesarovic.
Reflexive Control⤓ .md 2026-07-15T045513.000 000000000019720 Vladimir Lefebvre, Soviet military-strategic research, 1960s-1970s. Formalized in "Algebra of Conscience" and reflexive game theory. Developed to model decision-making in adversarial contexts where each party reasons about the other's reasoning.
Requisite Variety⤓ .md 2026-07-15T045515.000 000000000022784 W. Ross Ashby's Law of Requisite Variety (1956), extensively adopted and applied in Soviet organizational cybernetics by Glushkov, Berg, and the OGAS project team. The law states: "Only variety can destroy variety." Soviet cyberneticians used it as a theoretical basis for critiquing over-centralized control and designing distributed systems.
