With the aid of a Fermi-Walker chart associated with an orthonormal frame attached to a timelike curve in space-time, a discussion is given of relativistic balance laws that may be used to construct models of massive particles with spin, electric charge and a magnetic moment, interacting with background electromagnetic fields and gravitation described by non-Riemannian geometries. A natural generalization to relativistic Cosserat media is immediate.
Analyses for the first time relativistic particle-field-dynamics in terms of variational identities associated with a non-Riemannian space-time structure. Has led to a new and powerful tool for exploring developments in experimental gravitation and electrodynamics. RAE_import_type : Journal article RAE_uoa_type : Physics
