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 topology, in multivariable calculus, the differential of a smooth map between Euclidean spaces or differentiable manifolds is the approximating linear map between the tangent spaces, called pushforward (differential)
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
