In mathematics, the coset construction (or GKO construction) is a method of constructing unitary highest weight representations of the Virasoro algebra, introduced by Peter Goddard, Adrian Kent and David Olive (1986). The construction produces the complete discrete series of highest weight representations of the Virasoro algebra and demonstrates their unitarity, thus establishing the classification of unitary highest weight representations.

Cosets generated by elements of cosets
What were to happen should we generate a left or right coset with an element of a coset? In this video I explore how we simply end up with the same coset.

A graphical representation of cosets using Caley tables, gives us a deeper insight. In this video we explore two cases. In the first, the element of G that creates the coset of the subgroup is in the subgroup and in the second, it is not.

Abstract Algebra - 7.1 Cosets and Their Properties
In this video, we explore the definition of both left and right cosets and an example of each. In addition, we take a look at 9 properties that cosets share. Video Chapters: Intro 0:00 What is a Coset/Left Coset Example? 0:06 Example of Right Cosets 4:31 The First 3 Coset Properties 8:19

The Hoover Dam: an Engineering and Artistic Masterpiece
Located on the border between Arizona and Nevada, the Hoover Dam is an iconic structure that has stood the test of time for nearly a century. Built in the 1930s to provide hydroelectric power and help control floods in the Colorado River, the Hoover Dam is a testament to human ingenuity an

In this first video on cosets, I show you the equivalence relation on a group, G, that will turn out to create equivalence classes, which are actually cosets. We will prove later that these equivalence classes created by an element in the group, G, are equal to the set of element made up

EDIT: At 2:00, the columns for cosets of H={e, (12)} are switched. Abstract Algebra: We define normal subgroups and show that, in this case, the space of cosets carries a group structure, the quotient group. Example include S3, the modular integers, and Q/Z. U.Reddit course materia

GT3. Cosets and Lagrange's Theorem
Abstract Algebra: Let G be a group with subgroup H. We define an equivalence relation on G that partitions G into left cosets. We use this partition to prove Lagrange's Theorem and its corollary. U.Reddit course materials available at http://ureddit.com/class/23794/intro-to-group-theor

Complete Derivation: Universal Property of the Tensor Product

Why Normal Subgroups are Necessary for Quotient Groups
Proof that cosets are disjoint: https://youtu.be/uxhAUmgSHnI In order for a subgroup to create a quotient group (also known as factor group), it must be a normal subgroup. That means that when we conjugate an element in the subgroup, it stays in the subgroup. In this video, we explain wh
