... the left by G inverse conjugation because that's what it is then we might say the normal subgroups are closed under conjugation.

A VERY important concept of group theory, but often taught without any intuition, so much that it often confuses a lot of people ...

Visual Group Theory, Lecture 3.3: Normal subgroups A subgroup H of G is normal if every left coset gH equals the right coset Hg.

Proof that cosets are disjoint: https://youtu.be/uxhAUmgSHnI In order for a subgroup to create a quotient group (also known as ...

Jacob explains how homomorphisms and their kernels give rise to quotient groups, and sketches a proof of the First Isomorphism ...

Normal subgroups and ideals are similar. They are both used to define quotient groups/ rings or fields.

I'm going to talk about normal subgroups so as a reminder I have a group G and N is a subgroup we say that N is normal if for all g ...

In this video, we define what it means for a subgroup to be normal in a group, and look at a few examples.

Examining normal subgroups, via their unwieldy original definition.

How can a group be "broken apart" in a way that permits its reconstruction via a product? What is the "missing factor" in the ...

In Group Theory from Abstract Algebra, if we are given a group G and a subgroup H of G, we say that H is a normal subgroup of G, ...

We introduce normal subgroups.

Okay, so with that let me define an important concept of normal subgroups, which is related to both the notion of subgroups and ...
