WebLinear elasticity is a mathematical model of how solid objects deform and become internally stressed due to prescribed loading conditions. It is a simplification of the more general … In short, Christoffel symbols are symmetric in the two lower indices, meaning that these indices can be interchanged freely (Γ λ µν =Γ λ νµ). This is due to the fact that Christoffel symbols are defined as connection coefficients for a torsion-free connection, which requires them to be symmetric.
