Before we carry on with our coset journey, we need to discover when the left- and right cosets are equal to each other. The obvious situation is when our group is Abelian. The other situation is when the subgroup is a normal subgroup. In this video I show you what a normal subgroup is a

Abstract Algebra - 9.2 Factor Groups
Closely related to our study on normal subgroups, we now look at factor groups (aka quotient groups). These are groups created by partitioning a group according to a subgroup. We essentially divide the group by the subgroup, thus the name! Video Chapters: Intro 0:00 Recall a Normal Subgro

Katrin Tent: Sharply 2-transitive groups Abstract Finite sharply 2-transitive groups were classified by Zassenhaus in the 1930s and were shown to have regular abelian normal subgroups. While there were partial results in the infinite setting the question whether the same holds for infini

Nicolás Matte Bon: Confined subgroups and high transitivity
A subgroup of a group is confined if the closure of its conjugacy class in the Chabauty space does not contain the trivial subgroup. Such subgroups arise naturally as stabilisers for non-free actions on compact spaces. I will explain a result establishing a relation between the confined su

Difference Between Normalizer, Centralizer, and Stabilizer
