Conjugacy class

Visual Group Theory, Lecture 3.7: Conjugacy classes

Visual Group Theory, Lecture 3.7: Conjugacy classes We were first introduced to the concept of conjugacy when studying normal subgroups: H is normal if every conjugate of H is equal to H. Alternatively, we can fix an element x of G, and ask: "which elements can be written as conjugates o

Conjugacy classes of a group

After the previous video on conjugation, we can now look at conjugacy classes. You can learn more about Mathematica on my Udemy courses: https://www.udemy.com/mathematica/ https://www.udemy.com/mathematica-for-statistics/

Cycle types and conjugacy classes of the symmetric group

Cycle types refer to the order of the cycles that a permutation can be decomposed in. The symmetric group gives us another way to examine this topic and how it relates to conjugation classes.

GT18. Conjugacy and The Class Equation

Abstract Algebra: We consider the group action of the group G on itself given by conjugation. The orbits, called conjugacy classes, partition the group, and we have the Class Equation when G is finite. We also show that the partition applies to normal subgroups. Finally we apply the cla

G. Lusztig - Stratifying reductive groups

We define a decomposition of a reductive group into finitely many strata. The largest stratum is the set of regular elements, the smallest stratum is the centre.
