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.". Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Oct 10, 2019 · We can calculate the covariance between two asset returns given the joint probability distribution.

Oct 10, 2019 · We can calculate the covariance between two asset returns given the joint probability distribution. Consider the following example: Example. Suppose we wish to find the variance of each asset and the covariance between the returns of ABC and XYZ, given that the amount invested in each company is $1,000.

Thus, for a vector field W = f 1 U 1 + f 2 U 2, the covariant derivative formula (Lemma 3.1) reduces to jmenuji se Dominik Kovařík a obchoduji akcie, komodity, akciové indexy a měny s opcemi od roku 2008. Nejsem žádný guru!

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 $\Gamma^{\sigma}_{\mu \beta}$.
