WebAug 27, 2015 · The Christoffel symbol is not a tensor (notice it is not called the Christoffel tensor), but it could still be represented by a "3D box of numbers." The matrices g j l, g i l, and g i j are all the same, but when we assign specific values to i, j, and l, these terms reference different elements of the matrix. WebMar 10, 2024 · The Christoffel symbol does not transform as a tensor, but rather as an object in the jet bundle. More precisely, the Christoffel symbols can be considered as functions on the jet bundle of the frame bundle of M, …
