Classification of infinitesimal symmetries in covariant classical mechanics
Marco Modugno, Dirk Saller and Jürgen Tolksdorf
In the framework of general relativistic classical mechanics on a spacetime with absolute time, we classify the infinitesimal symmetries of the classical structure by means of distinguished Lie subalgebras of the Lie algebra of "special phase functions"".
These subalgebras are crucial also for the classification of infinitesimal quantum symmetries, which will be analysed in a forthcoming paper.
