(calculus) a type of differential equation in which the derivative of the unknown function at a certain time is given in terms of the values of the function at previous times

(mechanics) A type of differential that allows its output shafts to rotate at different speeds but can limit the maximum difference in angular velocity between the output shafts, allowing greater torque to be applied to the slower-spinning shaft(s) and generally resulting in better traction than older-design differentials.

(mathematics) The equation that defines the Legendre polynomials: d/dx[(1-x²)d/dxP_n(x)]+n(n+1)P_n(x)=0.

plural of limited-slip differential

plural of differential thermal analysis

(mathematical analysis, dated or historical) Ricci calculus; the rules of index notation and manipulation for tensors and tensor fields, as developed by Gregorio Ricci-Curbastro.

(differential geometry) A type of differential geometry in which the differential invariants studied are invariant under volume-preserving affine transformations.
