Description:    
We shall cover most of our textbook. We will cover roughly one section per 
lecture. However, some sections will require two or more lectures. 
It is helpful to read the text before class. 
Topics to be covered include elementary number theory, 
permutations, groups, subgroups, homomorphisms and factor groups, 
rings, ideals and factor rings, fields, and extension fields. 
Modern abstract algebra has a wide variety of applications: 
mathematics itself, physics, automata and theoretical computer science, 
cryptography and information theory, biology, and others. 
We will see some applications in the class. 
There are several goals of this class: to introduce you to 
modern abstract algebra (groups and rings), to expose you 
to the axiomatic approach in modern mathematics, and last but 
not least to make you more familiar with proofs.
Textbook:  
           
J. and L. Gilbert,
Elements of modern algebra, fifth edition
Exams: Exams will draw from material covered in class, that is, any theorems, proofs, example, or homework problem that we cover in class is a possible material for the tests. So, the best way to prepare for the exams will be to start with your class notes. There will be two in-class exams and a comprehensive final. Dates see above.
Homework: You learn more by doing, than by watching others give demonstrations. Therefore, homework is very important. When you sit down to do your homework is when you realize whether or not you understood the material from class. You also learn by practice, so do as many of the examples assigned as possible. I will assign homework on a regular basis. Your solutions should be written up with your best effort at explanation and should be neat. These problems will challenge your problem solving abilities. You may work in groups provided you follow the following guidelines: each person must write up each problem in their own words, no copying. Whenever you would like to discuss the class material, have any questions or are stuck on the homework, please visit me in my office either during my office hours or by appointment. l. thoma
Project:    
The purpose of the project is that you learn to work with literature
and other sources of information. The project has been distributed in class. 
If you do not have a copy, please let me know. 
The project is due Monday April 26. However, feel free to 
show me a draft version earlier for comments. 
 
Grading:    
Your grade will be based on your  exam scores, final exam score,
project, and homework grades. 
  homework    25% 
 
  in-class exams    20%  each 
 
  project    10%  
  final      25%  
 
Suggestions:  
  1.   Read the book carefully. 
I chose this book because I believe it gives 
nice explanations. It is helpful to read sections before we talk 
about them in class. 
  2.  
Do all of the homework assigned. If you don't gain 
experience in doing the problems yourself, it will be hard to remember 
how to do them on a test. It is helpful to start study groups 
and work together on homework. I do believe that how well you do in 
this course will depend on how well you study. 
  3.  
Attend class to keep current, ask questions, and learn knew topics. 
Also, attending class allows you to see what is emphasized. Remember the
material for the tests will come from what was emphasized. 
    
  4.  
Be sure to keep current of all topics. You will need to study 
a little almost everyday. If you don't understand something, don't let 
it wait too long because the concepts in this class build, one upon 
the next. You don't want the ``snowball effect'' to take over. 
  5.  
You may not understand an idea at first. Give it time to sink in. 
Sometimes you must go over it several times before it begins to make sense. 
It is not unusual for someone to be stuck on a particular kind of problem 
and not understand it in class. You may need to have it explained again, 
later. Please feel free to ask me to do so outside of class.
