kind. Transformations of the general coordinates. Symmetries and conservation
laws, Noether's theorem. Small oscillations: normal coordinates. Hamilton's
principle of the least action. General properties of the Langrange function,
space-time symmetries and conservation theorems. Gauge transformation.
