Purpose: The aim of this course is to provide a basic graduate level introduction to algebra. Sophisticated algebraic tools are fundamental not only in algebraic geometry and number theory but also in topology, mathematical physics, combinatorics and theoretical computer science.

Course description: I will follow quite closely Hungerford's text, covering most of the first six chapters; and if time permits, I will cover one or more of the following additional topics: elementary commutative algebra (from Chapter VIII), some basic facts concerning matroids (combinatorial geometry) and fundamentals of algebraic topology.

This course is a graduate course, while the prerequisits are minimal the pace will be fast and I intend to cover large amount of material quickly. If you are interested in a more relaxed introduction to algebra, I suggest taking another related course like 21-342 (Linear Algebra II) or 21-374 (Field Theory) instead.

There will be an emphasis on doing many exercises. Every week I will assign fairly large number of homework exercises which are due for the next Wedensday. Due to lack of a TA and a grader, homework will be collected on a random basis but will be graded carefully. Since I consider ability to prove (easy) theorems essential in this course, it will be impossible to pass the course without doing most of the homework assignments! A significant portion of the tests will include exercises similar to homework assignments.

Text:"Algebra" by Thomas W. Hungerford. Published by Springer-Verlag's Graduate Text books series (GTM 73) price comparison.

Test Dates: The first test was held on Wednesday, February 16. The second midterm will be held on Wednesday, April 20th.

The grades of the first test: 100x6, 98, 90x3, 85, 80x2, 65x2 and 45.

Evaluation: There will be two one hour tests (in class), weekly homework assignments, and a three hour final. These will be weighted as follows:

• Each of the two midterm tests will make up 20% of the grade
  
• The final will make up 50% of the grade
  
• Homework assignments should be ready for the Wedensday lecture, they will be collected randomly. They make up 10% of the grade.
  

Prerequisites: Algebraic Structures (21-373) and Linear Algebra I (21-341) or equivalent.
