  2. Stability theory - Wikipedia

    en.wikipedia.org/wiki/Stability_theory

    In mathematics, stability theory addresses the stability of solutions of differential equations and of trajectories of dynamical systems under small perturbations of initial conditions. The heat equation , for example, is a stable partial differential equation because small perturbations of initial data lead to small variations in temperature ...

  3. Hegemonic stability theory - Wikipedia

    en.wikipedia.org/wiki/Hegemonic_stability_theory

    Hegemonic stability theory (HST) is a theory of international relations, rooted in research from the fields of political science, economics, and history.HST indicates that the international system is more likely to remain stable when a single state is the dominant world power, or hegemon. [1]

  5. Lyapunov stability - Wikipedia

    en.wikipedia.org/wiki/Lyapunov_stability

    The mathematical theory of stability of motion, founded by A. M. Lyapunov, considerably anticipated the time for its implementation in science and technology. Moreover Lyapunov did not himself make application in this field, his own interest being in the stability of rotating fluid masses with astronomical application.

  6. Stable theory - Wikipedia

    en.wikipedia.org/wiki/Stable_theory

    In the mathematical field of model theory, a theory is called stable if it satisfies certain combinatorial restrictions on its complexity. Stable theories are rooted in the proof of Morley's categoricity theorem and were extensively studied as part of Saharon Shelah's classification theory, which showed a dichotomy that either the models of a theory admit a nice classification or the models ...

  9. Root locus analysis - Wikipedia

    en.wikipedia.org/wiki/Root_locus_analysis

    Spirule. In control theory and stability theory, root locus analysis is a graphical method for examining how the roots of a system change with variation of a certain system parameter, commonly a gain within a feedback system.
