Generalized Kac–Moody algebras are also sometimes called GKM algebras, Borcherds–Kac–Moody algebras, ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized Korteweg–De Vries equation Summary Generalized_Korteweg–De_Vries_equation In mathematics, a generalized Korteweg–De Vries equation (Masayoshi Tsutsumi, Toshio Mukasa & Riichi Iino 1970) is the nonlinear partial differential equation ∂ t u + ∂ x 3 u + ∂ x f ( u ) = 0. {\displaystyle \partial _{t}u+\partial _... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Multi-dimensional arithmetic progression Summary Multi-dimensional_arithmetic_progression In mathematics, a generalized arithmetic progression (or multiple arithmetic progression) is a generalization of an arithmetic progression equipped with multiple common differences – whereas an arithmetic progression is generated ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized conic Summary Generalized_conic In mathematics, a generalized conic is a geometrical object defined by a property which is a generalization of some defining property of the classical conic. For example, in elementary geometry, an ellipse can be defined as the locus of a point which moves in a plane such tha... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized conic Summary Generalized_conic In rectangular Cartesian coordinates, the equation y = x2 represents a parabola. The generalized equation y = x r, for r ≠ 0 and r ≠ 1, can be treated as defining a generalized parabola. The idea of generalized conic has found applications in approximation theory and optimiza... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized conic Summary Generalized_conic The starting point for this approach is to look upon an ellipse as a curve satisfying the 'two-focus property': an ellipse is a curve that is the locus of points the sum of whose distances from two given points is constant. The two points are the foci of the ellipse. The curv... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized conic Summary Generalized_conic Generalized conics with three foci are called trifocal ellipses. This can be further generalized to curves which are obtained as the loci of points such that some weighted sum of the distances from a finite set of points is a constant. A still further generalization is possib... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized conic Summary Generalized_conic Finally, the restriction that the set of fixed points, called the set of foci of the generalized conic, be finite may also be removed. The set may be assumed to be finite or infinite. | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized conic Summary Generalized_conic In the infinite case, the weighted arithmetic mean has to be replaced by an appropriate integral. Generalized conics in this sense are also called polyellipses, egglipses, or, generalized ellipses. Since such curves were considered by the German mathematician Ehrenfried Walth... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Closure with a twist Generalized cwatset Closure_with_a_twist > Generalized cwatset In mathematics, a generalized cwatset (GC-set) is an algebraic structure generalizing the notion of closure with a twist, the defining characteristic of the cwatset. | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized flag manifold Summary Flag_manifold In mathematics, a generalized flag variety (or simply flag variety) is a homogeneous space whose points are flags in a finite-dimensional vector space V over a field F. When F is the real or complex numbers, a generalized flag variety is a smooth or complex manifold, call... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized flag manifold Summary Flag_manifold For partial flags, one needs to specify the sequence of dimensions of the flags under consideration. For subgroups of the linear group, additional conditions must be imposed on the flags. In the most general sense, a generalized flag variety is defined to mean a projectiv... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Generalized flag manifold Summary Flag_manifold If X has an F-rational point, then it is isomorphic to G/P for some parabolic subgroup P of G. A projective homogeneous variety may also be realised as the orbit of a highest weight vector in a projectivized representation of G.
