Quantization condition Mathematical formulation Dirac_monopole > Topological interpretation > Mathematical formulation It generalizes to d + 1 dimensions with d ≥ 2 in several ways. One way is to extend everything into the extra dimensions, so that U(1) monopoles become sheets of dimension d − 3.

Coherent ring Summary Coherent_ring In mathematics, a (left) coherent ring is a ring in which every finitely generated left ideal is finitely presented. Many theorems about finitely generated modules over Noetherian rings can be extended to finitely presented modules over coherent rings. Every left Noetherian ring is l... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Coherent ring Summary Coherent_ring The ring of polynomials in an infinite number of variables over a left Noetherian ring is an example of a left coherent ring that is not left Noetherian. A ring is left coherent if and only if every direct product of flat right modules is flat (Chase 1960), (Anderson & Fuller 1992, p... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Monge-Ampere equation Summary Monge–Ampère_equation In mathematics, a (real) Monge–Ampère equation is a nonlinear second-order partial differential equation of special kind. A second-order equation for the unknown function u of two variables x,y is of Monge–Ampère type if it is linear in the determinant of the Hessian ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Monge-Ampere equation Summary Monge–Ampère_equation The most complete results so far have been obtained when the equation is elliptic. Monge–Ampère equations frequently arise in differential geometry, for example, in the Weyl and Minkowski problems in differential geometry of surfaces. They were first studied by Gaspar... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Bounded interval Summary Non-degenerate_interval In mathematics, a (real) interval is a set of real numbers that contains all real numbers lying between any two numbers of the set. For example, the set of numbers x satisfying 0 ≤ x ≤ 1 is an interval which contains 0, 1, and all numbers in between. Other examples of in... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Bounded interval Summary Non-degenerate_interval The concept of measure can then be extended to more complicated sets of real numbers, leading to the Borel measure and eventually to the Lebesgue measure.

Leibniz algebra Summary Leibniz_algebra They attracted interest after Jean-Louis Loday noticed that the classical Chevalley–Eilenberg boundary map in the exterior module of a Lie algebra can be lifted to the tensor module which yields a new chain complex. In fact this complex is well-defined for any Leibniz algebra. Th... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Leibniz algebra Summary Leibniz_algebra If L is the Lie algebra of (infinite) matrices over an associative R-algebra A then Leibniz homology of L is the tensor algebra over the Hochschild homology of A.

Dualizing object Summary Dualizing_object In mathematics, a *-autonomous (read "star-autonomous") category C is a symmetric monoidal closed category equipped with a dualizing object ⊥ {\displaystyle \bot } .

*-algebra *-ring Involutive_ring > Definitions > *-ring In mathematics, a *-ring is a ring with a map *: A → A that is an antiautomorphism and an involution. More precisely, * is required to satisfy the following properties: (x + y)* = x* + y* (x y)* = y* x* 1* = 1 (x*)* = xfor all x, y in A.

*-algebra *-ring Involutive_ring > Definitions > *-ring One can define a sesquilinear form over any *-ring. Also, one can define *-versions of algebraic objects, such as ideal and subring, with the requirement to be *-invariant: x ∈ I ⇒ x* ∈ I and so on. *-rings are unrelated to star semirings in the theory of computat... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
2-valued morphism Summary 2-valued_morphism In mathematics, a 2-valued morphism is a homomorphism that sends a Boolean algebra B onto the two-element Boolean algebra 2 = {0,1}. It is essentially the same thing as an ultrafilter on B, and, in a different way, also the same things as a maximal ideal of B. 2-valued morphi... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
3-manifold Summary 3-manifold In mathematics, a 3-manifold is a topological space that locally looks like a three-dimensional Euclidean space.
