Abstract

The general structure of equations of motion for test particles is considered with the help of a Lagrangian principle postulating a minimal coupling between internal and external variables. As an example the case of the Lorentz group as the basic internal group is considered in more detail. The connection with the Mathisson‐Papapetrou equations is established.

Conventional molecular dynamics simulations of macromolecules require long computational times because the most interesting motions are very slow compared to the fast oscillations of bond lengths and bond angles that limit the integration time step. Simulation of dynamics in the space of internal co
