General Information
- See
Undergrad Course Description
- MWF at 10:00-11:00 AM in DRL 4C4.
First class on We, Aug 29, 2019.
- This is the second part of a (rigorous proof based)
introduction to Algebra. For a passing grade,
the students are expected to:
- Understand and know the material and be able to solve
related problems.
- Understand rigorous mathematical argumentation/proofs
and to be able to write coherent mathematical proofs.
- Syllabus:
Rings: Basic facts, Examples
(polynomial rings, matrix rings, group rings, etc.);
Subrings, Ideals, Ring homomorphisms,
Quotient rings; Prime ideals, Maximal ideals, Comaximal ideals,
Chinese Remainder Thm; Rings of fractions. Special classes
of rings: Euclidean domains, Principal Ideal Domains, Unique
factorization Domains. More on rings of polynomials.
Modules and Vector spaces: Basic facts, Examples;
Homomorphisms, Isomorphism Thm. Multilinear Forms
and Tensor Product. Finite modules over PID, Application:
The Jordan Canonical Form. Fields: Basic facts, Examples,
Finite Fields, Fields of fractions. Field Extensions, Algebraic
(in)dependence, Algebraic extensions, Algebraic closure.
Splitting fields, The fundamental Theorem of Galois
Theory, Examples of Galois groups. Cyclotomic Fields,
Straightedge & Compass constructions. Impossibility
of resolving the quintic.
- Required background/prerequisites: Basic
facts about sets and maps, familiarity with proofs, groups
(as in Math 370), linear algebra (as in Math 314),
- Resources:
There are several books you can use (and some course
notes might/will be provided).
- Abstract Algebra by Dummit & Foote
(3rd Edition), Part II, Part III (most of this is linear
algebra, which you should be familiar with), Part IV.
- A first course in Abstract Algebra by Raleigh
(7th edition), Ch: IV, V, VI, IX, X. Especially if you are
not very familiar with proofs, you might find this text very
useful/appealing.
- Serge Lang, Algebra, Springer Verlag,
standard reference text which contains a very large
amount of material.
Basic Rules:
- The final grade is based on midterms and a final exam
(30%+30%) and everything else (40%). "Everything else" consists
of regular homework, participation/performance in class, etc.
- Exam dates (tentatively): Oct 5, Nov 9, Dec 7, 2018.
- Miscellannia: Announcements, homework assignment, notes,
etc., will all be posted on web. No hard copies will be distributed. Please
check this page frequently for the most updated information. Remember
to use to RELOAD button of your browser.
- Homework:
- Homework will be assigned each week, and in oder to see the
homework please follow the links under
Homework
Math 371. The homework assignment of each week is tentatively
due on Wednesday of the next week.
- Your works should contain complete solutions, and rigorous and
logically correct proofs for theoretical problems. (Note: such a proof
must be written in grammatically correct language.)
- You are encouraged to work in groups and
discuss/communicate with each other as much as possible.
But the work you hand in must be your own write-up.
- Late work will not be accepted.
- Grading Note: At the end of the semester, everyone who has not
withdrawn from the class will get a grade. The grade "I" (Incomplete)
will not be given to avoid the grade "F" (Fail).
