In the mathematical fields of differential geometry and tensor calculus, differential forms are an approach to multivariable calculus that is independent of coordinates. Differential forms provide a unified approach to defining integrands over curves, surfaces, volumes, and higher-dimensional manifolds.
 The modern notion of differential forms was pioneered by Élie Cartan.
 It has many applications, especially in geometry, topology and physics.
Tullio Levi-Civita, FRS (29 March 1873 – 29 December 1941; ] ) was an Italian mathematician, most famous for his work on absolute differential calculus (tensor calculus) and its applications to the theory of relativity, but who also made significant contributions in other areas.
 He was a pupil of Gregorio Ricci-Curbastro, the inventor of tensor calculus.
 His work included foundational papers in both pure and applied mathematics, celestial mechanics (notably on the three-body problem), analytic mechanics (the Levi-Civita separability conditions in the Hamilton–Jacobi equation) and hydrodynamics.
The calculus of moving surfaces (CMS) is an extension of the classical tensor calculus to deforming manifolds. Central to the CMS is the formula_1-derivative whose original definition was put forth by Jacques Hadamard.
 It plays the role analogous to that of the covariant derivative formula_2 on differential manifolds.
 In particular, it has the property that it produces a tensor when applied to a tensor.
Gregorio Ricci-Curbastro (] ; 12January 1925) was an Italian mathematician born in Lugo di Romagna.
 He is most famous as the inventor of tensor calculus, but also published important works in other fields.
In mathematics, tensor calculus or tensor analysis is an extension of vector calculus to tensor fields (tensors that may vary over a manifold, e.g. in spacetime).
Eugenio Beltrami (16 November 1835 – 18 February 1900) was an Italian mathematician notable for his work concerning differential geometry and mathematical physics.
 His work was noted especially for clarity of exposition.
 He was the first to prove consistency of non-Euclidean geometry by modeling it on a surface of constant curvature, the pseudosphere, and in the interior of an "n"-dimensional unit sphere, the so-called Beltrami–Klein model.
 He also developed singular value decomposition for matrices, which has been subsequently rediscovered several times.
 Beltrami's use of differential calculus for problems of mathematical physics indirectly influenced development of tensor calculus by Gregorio Ricci-Curbastro and Tullio Levi-Civita.
Elwin Bruno Christoffel (] ; November 10, 1829 – March 15, 1900) was a German mathematician and physicist.
 He introduced fundamental concepts of differential geometry, opening the way for the development of tensor calculus, which would later provide the mathematical basis for general relativity.
In mathematics, Ricci calculus constitutes the rules of index notation and manipulation for tensors and tensor fields.
 It is also the modern name for what used to be called the absolute differential calculus (the foundation of tensor calculus), developed by Gregorio Ricci-Curbastro in 1887–1896, and subsequently popularized in a paper written with his pupil Tullio Levi-Civita in 1900.
 Jan Arnoldus Schouten developed the modern notation and formalism for this mathematical framework, and made contributions to the theory, during its applications to general relativity and differential geometry in the early twentieth century.
Jan Arnoldus Schouten (28 August 1883 – 20 January 1971) was a Dutch mathematician and Professor at the Delft University of Technology.
 He was an important contributor to the development of tensor calculus and Ricci calculus, and was one of the founders of the Mathematisch Centrum in Amsterdam.
In mathematics, particularly in linear algebra, tensor analysis, and differential geometry, the Levi-Civita symbol represents a collection of numbers; defined from the sign of a permutation of the natural numbers 1, 2, …, "n" , for some positive integer n .
 It is named after the Italian mathematician and physicist Tullio Levi-Civita.
 Other names include the permutation symbol, antisymmetric symbol, or alternating symbol, which refer to its antisymmetric property and definition in terms of permutations.
