In theoretical physics, general covariance, also known as diffeomorphism covariance or general invariance, consists of the invariance of the form of physical laws under arbitrary differentiable coordinate transformations. Covariance is the measure of changes between two random variables in statistics. Learn about its types and how it differs from correlation along with formulas and the solved example here at BYJU'S. In physics, a covariant transformation is a rule that specifies how certain entities, such as vectors or tensors, change under a change of basis.The transformation that describes the new basis vectors as a linear combination of the old basis vectors is defined as a covariant transformation. One can motivate the covariant differentiation using only vector calculus. It works for an oversimplified case though (but since the OP doesn't accept either the definition via Ehresmann connection nor the vector bundle definition, may be it's justified.) Many text books on differential geometry motivate covariant derivative more or less by saying that if you have a vector field along a curve on a manifold (that is a curve $\gamma(t)$ and an assignm Metric compatible. In the coordinate-specific section of this article, it is stated "By the way, this particular expression is equal to zero, because the covariant derivative of a function solely of the metric is always zero.".

Kovarianz erklärenHier bist du genau richtig, wenn für dich Mathe in der Schule wie chinesisch ist, wenn du dich sehr schnell und produktiv verbessern möchte Lecture # 8 General Relativity & Cosmology Lecture Series In mathematics, the covariant derivative is a way of specifying a derivative along tangent vectors of a manifold.Alternatively, the covariant derivative is a way of introducing and working with a connection on a manifold by means of a differential operator, to be contrasted with the approach given by a principal connection on the frame bundle – see affine connection. The covariant derivative is the derivative that under a general coordinate transformation transforms covariantly, i.e., linearly via the Jacobian matrix of the coordinate transformation. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. The connection is chosen so that the covariant derivative of the metric is zero. The vanishing covariant metric derivative is not a consequence of using "any" connection, it's a condition that allows us to choose a specific connection $\Gamma^{\sigma}_{\mu \beta}$. After the company’s founding in 2005, YouTube rose quickly through the ranks of online video websites to become an industry leader that streams more than a billion hours of video a day.
