Cyclic Groups, Generators, and Cyclic Subgroups | Abstract Algebra
We introduce cyclic groups, generators of cyclic groups, and cyclic subgroups. We discuss an isomorphism from finite cyclic groups to the integers mod n, as well as an isomorphism from infinite cyclic groups to the integers. We establish a cyclic group of order n is isomorphic to Zn, and a

Cyclic Groups (Abstract Algebra)
Cyclic groups are the building blocks of abelian groups. There are finite and infinite cyclic groups. In this video we will define cyclic groups, give a list of all cyclic groups, talk about the name βcyclic,β and see why they are so essential in abstract algebra. Be sure to subscribe s

Every Cyclic Group is Abelian | Abstract Algebra
We prove every cyclic group is abelian by taking two arbitrary elements from an arbitrary cyclic group and showing they commute. Recall a cyclic group is entirely generated by all powers of a particular element. #abstractalgebra #grouptheory Cyclic Groups, Generators, and Cyclic Subgroup
From playlist Abstract Algebra
Cyclic groups are first and foremost, as the term implies, groups. What makes them cyclic is that at least on of the elements in the set that makes up the group under a specific binary operation can generate the group by performing the binary operation on itself. So, if a is an element o

Lecture 10: The circle action on THH
In this video we construct an action of the circle group S^1 = U(1) on the spectrum THH(R). We will see how this is the homotopical generalisation of the Connes operator. The key tool will be Connes' cyclic category. The speaker is of course Achim Krause and not Thomas Nikolaus as falsely
