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://

Abstract Algebra | Every PID is a UFD.
We prove the classical result in commutative algebra that every principal ideal domain is in fact a unique factorization domain. Along the way, we introduce the ascending chain condition and the notion of a Noetherian ring. Please Subscribe: https://www.youtube.com/michaelpennmath?sub_co

RNT1.4. Ideals and Quotient Rings
Ring Theory: We define ideals in rings as an analogue of normal subgroups in group theory. We give a correspondence between (two-sided) ideals and kernels of homomorphisms using quotient rings. We also state the First Isomorphism Theorem for Rings and give examples.

Visual Group Theory: Lecture 7.4: Divisibility and factorization The ring of integers have a number of properties that we take for granted: every number can be factored uniquely into primes, and all pairs of numbers have a unique gcd and lcm. In this lecture, we investigate when this happ

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:

Order of Elements in a Group | Abstract Algebra
We introduce the order of group elements in this Abstract Algebra lessons. We'll see the definition of the order of an element in a group, several examples of finding the order of an element in a group, and we will introduce two basic but important results concerning distinct powers of ele

Unique Factorization - Feb 08, 2021 - Rings and Modules
We introduce the Noetherianity hypothesis on rings and show that under this hypothesis that one can factor elements into a product of irreducible elements.

Commutative algebra 24 Artinian modules
This lecture is part of an online course on commutative algebra, following the book "Commutative algebra with a view toward algebraic geometry" by David Eisenbud. We define Artinian rings and modules, and give several examples of them. We then study finite length modules, show that they
