“…The uniform motion of the physical system, in particular, a mechanism defined along with the particle in a given appropriate spacetime structure, can be described by minimizing the action functional and can further computation be obtained by the principle of the least action [33][34][35]. The investigation of the uniform motion of the particle is very efficient for the exact comprehension of many physical processes such as vortex filaments, integrable systems, dynamics of Heisenberg chain, soliton equation theory, relativity, sigma models, water wave theory, field theories, fluid dynamics, linear and nonlinear optics, and so on.…”
