WebCHRISTOFFEL SYMBOLS 657 If the basis vectors are not constants, the RHS of Equation F.7 generates two terms The last term in Equation F.8 is usually defined in terms of the Christoffel symboE rkj: The definition in Equation F.9 implies the result of the differentiation on the LHS must be a vector quantity, expressed in terms of the covariant basis vectors &. WebWhen the geodesic equation is written in the form of (5), we can identify the Christo el symbols by multiplying that equation by g : g = 1 2 @g @x + @g @x @g @x (14) which is the general relation for the Christo el symbols. This equation can be useful if the metric is diagonal in the coordinate system being used, as then the
WebThis is one form of the geodesic equation, which is a second order ordi-nary differential equation. (It’s an ordinary differential equation despite the appearance of the partial derivative @gij @xa because we will know the metric as a function of the coordinates, so this derivative will be known when we set out to solve the ODE.)
