- 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

- Differential of a function, represents a change in the linearization of a function
- Differential (pushforward) The total derivative of a map between manifolds.
