Riemannian Geometry
The symbol ∂ represents a partial derivative, which is a fundamental concept in calculus and differential geometry. It indicates the derivative of a function with respect to one of its variables while keeping the other variables constant. This concept is crucial in understanding how functions change in multidimensional spaces, especially in the study of affine connections and their properties.
