WebIn short, Christoffel symbols represent the connection coefficients of the Levi-Civita connection. In a geometric sense, they describe changes in basis vectors throughout a given coordinate system. Physically, the Christoffel symbols represent fictitious forces induced by a non-inertial reference frame. WebIn mathematics, the Laplace operator or Laplacian is a differential operator given by the divergence of the gradient of a scalar function on Euclidean space.It is usually denoted by the symbols , (where is the nabla operator), or .In a Cartesian coordinate system, the Laplacian is given by the sum of second partial derivatives of the function with respect to …
