differential

Differential may refer to:

==Mathematics== Differential (mathematics) comprises multiple related meanings of the word, both in calculus and differential geometry, such as an infinitesimal change in the value of a function Differential algebra Differential calculus Differential of a function, represents a change in the linearization of a function Total differential is its generalization for functions of multiple variables Differential (infinitesimal) (e.g. dx, dy, dt etc.) are interpreted as infinitesimals Differential equation, an equation relating derivatives of a function Differential topology Differential (pushforward) The total derivative of a map between manifolds. Differential exponent, an exponent in the factorisation of the different ideal Differential geometry, exterior differential, or exterior derivative, is a generalization to differential forms of the notion of differential of a function on a differentiable manifold Differential (coboundary), in homological algebra and algebraic topology, one of the maps of a cochain complex Differential cryptanalysis, a pair consisting of the difference, usually computed by XOR, between two plaintexts, and the difference of the corresponding ciphertexts
