Covariant Derivative

A covariant derivative of a vector field in the direction of the vector denoted is defined by the following properties for any vector v, vector fields u, w and scalar functions f and g:

  1. is algebraically linear in so
  2. is additive in so
  3. obeys the product rule, i.e. where is defined above.

Note that at point p depends on the value of v at p and on values of u in a neighbourhood of p because of the last property, the product rule.

Famous quotes containing the word derivative:

    Poor John Field!—I trust he does not read this, unless he will improve by it,—thinking to live by some derivative old-country mode in this primitive new country.... With his horizon all his own, yet he a poor man, born to be poor, with his inherited Irish poverty or poor life, his Adam’s grandmother and boggy ways, not to rise in this world, he nor his posterity, till their wading webbed bog-trotting feet get talaria to their heels.
    Henry David Thoreau (1817–1862)
