A Jacobi ellipsoid is a triaxial (i.e. scalene) ellipsoid under hydrostatic equilibrium which arises when a self-gravitating , fluid body of uniform density rotates with a constant angular velocity . It is named after the German mathematician Carl Gustav Jacob Jacobi . [ 1 ]

In Riemannian geometry , a Jacobi field is a vector field along a geodesic γ {\displaystyle \gamma } in a Riemannian manifold describing the difference between the geodesic and an "infinitesimally close" geodesic. In other words, the Jacobi fields along a geodesic form the tangent space to the geodesic in the space of ... | https://en.wikipedia.org/wiki/Jacobi_field |
In mathematics , the Jacobi identity is a property of a binary operation that describes how the order of evaluation, the placement of parentheses in a multiple product, affects the result of the operation. By contrast, for operations with the associative property , any order of evaluation gives the same result (parenth... | https://en.wikipedia.org/wiki/Jacobi_identity |
In mathematics , the Jacobi triple product is the identity:
for complex numbers x and y , with | x | < 1 and y ≠ 0. It was introduced by Jacobi ( 1829 ) in his work Fundamenta Nova Theoriae Functionum Ellipticarum .
The Jacobi triple product identity is the Macdonald identity for the affine root system of type A 1 , ... | https://en.wikipedia.org/wiki/Jacobi_triple_product |
In mathematics, a Jacobian , named for Carl Gustav Jacob Jacobi , may refer to: | https://en.wikipedia.org/wiki/Jacobian |
In mathematics , the Jacobian conjecture is a famous unsolved problem concerning polynomials in several variables . It states that if a polynomial function from an n -dimensional space to itself has Jacobian determinant which is a non-zero constant, then the function has a polynomial inverse. It was first conjectured i... | https://en.wikipedia.org/wiki/Jacobian_conjecture |
In vector calculus , the Jacobian matrix ( / dʒ ə ˈ k oʊ b i ə n / , [ 1 ] [ 2 ] [ 3 ] / dʒ ɪ -, j ɪ -/ ) of a vector-valued function of several variables is the matrix of all its first-order partial derivatives . If this matrix is square , that is, if the number of variables equals the number of components of function... | https://en.wikipedia.org/wiki/Jacobian_matrix_and_determinant |
In mathematics , the Jacobi–Anger expansion (or Jacobi–Anger identity ) is an expansion of exponentials of trigonometric functions in the basis of their harmonics. It is useful in physics (for example, to convert between plane waves and cylindrical waves ), and in signal processing (to describe FM signals). This identi... | https://en.wikipedia.org/wiki/Jacobi–Anger_expansion |
The Jacobi–Madden equation is the Diophantine equation
proposed by the physicist Lee W. Jacobi and the mathematician Daniel J. Madden in 2008. [ 1 ] [ 2 ] The variables a , b , c , and d can be any integers , positive, negative or 0. [ a ] Jacobi and Madden showed that there are an infinitude of solutions of this equa... | https://en.wikipedia.org/wiki/Jacobi–Madden_equation |
Jacobsen's catalyst is the common name for N,N'-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminomanganese(III) chloride, a coordination compound of manganese and a salen-type ligand . It is used as an asymmetric catalyst in the Jacobsen epoxidation , which is renowned for its ability to enantioselectively tra... | https://en.wikipedia.org/wiki/Jacobsen's_catalyst |
The Jacobsen epoxidation , sometimes also referred to as Jacobsen-Katsuki epoxidation is a chemical reaction which allows enantioselective epoxidation of unfunctionalized alkyl- and aryl- substituted alkenes. [ 1 ] [ 2 ] [ 3 ] It is complementary to the Sharpless epoxidation (used to form epoxides from the double bond ... | https://en.wikipedia.org/wiki/Jacobsen_epoxidation |
The Jacobsen rearrangement is a chemical reaction , commonly described as the migration of an alkyl group in a sulfonic acid derived from a polyalkyl- or polyhalobenzene:
The exact reaction mechanism is not completely clear, but evidence indicates that the rearrangement occurs intermolecularly and that the migrating g... | https://en.wikipedia.org/wiki/Jacobsen_rearrangement |
