[ANT04] Counting ideal classes
We don't always get unique factorisation. In those cases, can we measure how badly this uniqueness fails?

Abstract Algebra | Ideals of quotients of PIDs
We prove that every ideal of a quotient of a principal ideal domain is also principal. Notice that the new space may not be an integral domain, so it is sometimes called a principal ring. Please Subscribe: https://www.youtube.com/michaelpennmath?sub_confirmation=1 Personal Website: http:

Visual Group Theory, Lecture 7.3: Ring homomorphisms
Visual Group Theory, Lecture 7.3: Ring homomorphisms A ring homomorphism is a structure preserving map between rings, which means that f(x+y)=f(x)+f(y) and f(xy)=f(x)f(y) both must hold. The kernel is always a two-sided ideal. There are four isomorphism theorems for rings, which are compl

RNT2.1. Maximal Ideals and Fields
Ring Theory: We now consider special types of rings. In this part, we define maximal ideals and explore their relation to fields. In addition, we note three ways to construct fields.

Proof: Ideal of a Ring is Proper iff it has no Units | Abstract Algebra
An ideal of a ring with identity is proper if and only if the ideal contains no units of the ring. We prove this result in today's abstract algebra video lesson! Remember that an ideal, I, of a ring, R, is an additive subgroup of I such that for all r in R and x in I, r*x and x*r are also

Abstract Algebra | Principal Ideals of a Ring
We define the notion of a principal ideal of a ring and give some examples. We also prove that all ideals of the integers are principal ideals, that is, the integers form a principal ideal domain (PID). http://www.michael-penn.net https://www.researchgate.net/profile/Michael_Penn5 http://

Rings 6 Prime and maximal ideals
This lecture is part of an online course on rings and modules. We discuss prime and maximal ideals of a (commutative) ring, use them to construct the spectrum of a ring, and give a few examples. For the other lectures in the course see https://www.youtube.com/playlist?list=PL8yHsr3EFj5
