plural of differential form

plural of differentiable manifold

(differential geometry) A manifold that is locally similar enough to a Euclidean space (ℝⁿ) to allow one to do calculus;

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

(differential geometry, tensor calculus, sometimes as "differential p-form") A completely antisymmetric tensor (of order p) that is defined on a Riemannian manifold; an expression, derived by applying a formalism to said tensor, that represents an integrand over the manifold.

(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.

(automotive, mechanical engineering) Steering by means of driving the wheels or treads on one side of a vehicle faster than those on the other side, or driving the wheels or treads on one side in the forward and on the other side in the reverse direction.
