A Galois group G associated to a field extension L/K acts in a natural way on some abelian groups, for examp... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Galois ring Summary Galois_ring In mathematics, Galois rings are a type of finite commutative rings which generalize both the finite fields and the rings of integers modulo a prime power. A Galois ring is constructed from the ring Z / p n Z {\displaystyle \mathbb {Z} /p^{n}\mathbb {Z} } similar to how a finite field F ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Galois ring Summary Galois_ring Galois rings were studied by Krull (1924), and independently by Janusz (1966) and by Raghavendran (1969), who both introduced the name Galois ring. They are named after Évariste Galois, similar to Galois fields, which is another name for finite fields. Galois rings have found application... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Solvable by radicals Summary Galois_Theory In mathematics, Galois theory, originally introduced by Évariste Galois, provides a connection between field theory and group theory. This connection, the fundamental theorem of Galois theory, allows reducing certain problems in field theory to group theory, which makes them s... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Solvable by radicals Summary Galois_Theory This widely generalizes the Abel–Ruffini theorem, which asserts that a general polynomial of degree at least five cannot be solved by radicals. Galois theory has been used to solve classic problems including showing that two problems of antiquity cannot be solved as they were ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Solvable by radicals Summary Galois_Theory Galois' work was published by Joseph Liouville fourteen years after his death. The theory took longer to become popular among mathematicians and to be well understood. Galois theory has been generalized to Galois connections and Grothendieck's Galois theory. | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Gaussian brackets Summary Gaussian_bracket In mathematics, Gaussian brackets are a special notation invented by Carl Friedrich Gauss to represent the convergents of a simple continued fraction in the form of a simple fraction. Gauss used this notation in the context of finding solutions of the indeterminate equations o... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Gauss elimination Summary Gauss–Jordan_elimination In mathematics, Gaussian elimination, also known as row reduction, is an algorithm for solving systems of linear equations. It consists of a sequence of operations performed on the corresponding matrix of coefficients. This method can also be used to compute the rank o... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Gauss elimination Summary Gauss–Jordan_elimination To perform row reduction on a matrix, one uses a sequence of elementary row operations to modify the matrix until the lower left-hand corner of the matrix is filled with zeros, as much as possible. There are three types of elementary row operations: Swapping two rows, ... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Gauss elimination Summary Gauss–Jordan_elimination This final form is unique; in other words, it is independent of the sequence of row operations used. For example, in the following sequence of row operations (where two elementary operations on different rows are done at the first and third steps), the third and fourth... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Gaussian measure Summary Gaussian_measure In mathematics, Gaussian measure is a Borel measure on finite-dimensional Euclidean space Rn, closely related to the normal distribution in statistics. There is also a generalization to infinite-dimensional spaces. Gaussian measures are named after the German mathematician Carl... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
