Derivation
A derivation is a sequence of steps, logical or computational, from one result to another. The word derivation comes from the word "derive."
"Derivation" can also refer to a particular type of operator used to define a derivation algebra on a ring or algebra. In particular, let A be a Banach algebra and X be a Banach A-bimodule. Any element of
is called a bounded derivation of A in X and any element of
is called an inner derivation.
