WebNov 10, 2013 · In 1877 Christoffel published a paper on the propagation of plane waves in media with a surface discontinuity. This was an early contribution to the theory of shock waves and followed earlier work on one dimensional gas flows by Riemann. Christoffel was interested in the theory of invariants. He wrote six papers on this topic. Christoffel symbols play a key role in the mathematics of general relativity, but do they have some kind of physical interpretation as well? Physically, Christoffel symbols can be interpreted as describing fictitious forces arising from a non-inertial reference frame.
