Knit product Summary Knit_product In mathematics, especially group theory, the Zappa–Szép product (also known as the Zappa–Rédei–Szép product, general product, knit product, exact factorization or bicrossed product) describes a way in which a group can be constructed from two subgroups. It is a generalization of the di... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |

Normalizer (group theory) Summary Self-normalizing_subgroup In mathematics, especially group theory, the centralizer (also called commutant) of a subset S in a group G is the set C G ( S ) {\displaystyle \operatorname {C} _{G}(S)} of elements of G that commute with every element of S, or equivalently, such that conju... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Normalizer (group theory) Summary Self-normalizing_subgroup In ring theory, the centralizer of a subset of a ring is defined with respect to the semigroup (multiplication) operation of the ring. The centralizer of a subset of a ring R is a subring of R. This article also deals with centralizers and normalizers in a Lie... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Class number (group theory) Summary Conjugation_(group_theory) In mathematics, especially group theory, two elements a {\displaystyle a} and b {\displaystyle b} of a group are conjugate if there is an element g {\displaystyle g} in the group such that b = g a g − 1 . {\displaystyle b=gag^{-1}.} This is an equivalence r... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Class number (group theory) Summary Conjugation_(group_theory) In other words, each conjugacy class is closed under b = g a g − 1 {\displaystyle b=gag^{-1}} for all elements g {\displaystyle g} in the group. Members of the same conjugacy class cannot be distinguished by using only the group structure, and therefore sha... | https://www.kaggle.com/datasets/conjuring92/wiki-stem-corpus |
Five Lemma Summary Five_Lemma In mathematics, especially homological algebra and other applications of abelian category theory, the five lemma is an important and widely used lemma about commutative diagrams.
