A structured visual guide to the major mathematical areas and their relationships.
Search by code, branch, topic, subtopic, or a keyword from the descriptions.
This subtopic introduces the core ideas in dynamics of particle systems, including foundational concepts, standard methods, and the main questions used to organize the area. Typical uses include building mathematical background, framing related research problems, and supporting applications in neighboring fields where these concepts provide useful structure.
This topic studies the dynamics of spinning rigid bodies, especially gyroscopes, including precession, nutation, and the coupling of spin with external torques. It is a classical example of nontrivial rigid-body motion.
Used in navigation, aerospace, and control systems where rotational stability is central.
This topic studies the torque-free motion of a rigid body, including Euler equations, Poinsot motion, and the role of principal moments of inertia. It is one of the canonical examples of integrable rigid-body dynamics.
Used in satellite attitude dynamics, molecular modeling, and the study of symmetric top motion.
This topic studies perturbation expansions and asymptotic methods for nearly integrable rigid-body problems, including small-parameter expansions and secular behavior. It is a bridge between exact classical models and realistic systems with weak disturbances.
Perturbation theory (Wikipedia)
Used when exact solutions are unavailable and one needs controlled approximations for weakly perturbed rigid-body motions.
This topic studies special integrable cases of rigid-body and mechanical motion, where conserved quantities allow closed-form solutions or explicit reduction to simpler systems. Such cases illuminate the structure of more general dynamics.
Used to understand solvable models, benchmark numerical methods, and reveal the geometry behind more complicated trajectories.
This topic investigates the dynamics of systems composed of multiple interconnected rigid bodies, including constraints, joints, and internal forces. It is central to biomechanics, robotics, and mechanical simulation.
Used to model robotic arms, biomechanics, automotive systems, and other assemblies of linked bodies.
