WebApr 13, 2024 · The generalized Hessian operator \textrm {H}^ { (\nabla ,g)} (\xi ) is more interesting if the vector field \xi is closed. It is attached to a pair (\nabla ,g) of an affine connection and a (pseudo-)Riemannian metric and differs from the Hessian of a vector field, which is a (1, 2)-tensor field defined by means of an affine connection \nabla as. The symmetry may be broken if the function fails to have differentiable partial derivatives, which is possible if Clairaut's theorem is not satisfied (the second partial derivatives are not continuous). An example of non-symmetry is the function (due to Peano) (1) bombshell beauty lounge las vegas
