In Cartesian coordinates, the divergence of a continuously differentiable vector field is the scalar-valued function: As the name implies the divergence is a measure of how much vectors are diverging. The divergence of a tensor field of non-zero order k is written as , a contraction to a tensor field of order k − 1.
