Welcome to MAT 312 and AMS 351.
As the title of this course indicates we will cover some ideas in the theory of abstract algebra and apply some of these concepts to practical problems. The algebraic concepts covered will include the theory of goups, polynomials, rings and fields. Some of these ideas will be applied to the study of coding theory.
I will not be holding my usual office hours on WED. 10/14 and 10/21. Instead I will hold office hours from 8:30am-9:30am on MON. 10/12 and 10/19.

Problem sets will be assigned weekly; check this webpage for the assigments. Each homework set is due during your recitation class of the following week (unless otherwises stipulated). Note that the solutions to some of the problems appear in the back of the text book. You should nonetheless try and solve these problems without recourse to the answer key, and should write the problem up carefully in your own words even if you have consulted the book for the final answer: always show your work.
It is OK to discuss homework problems with other students. However, each student must write up the homework individually in his/her own words, rather than merely copying someone else's.
There will be one midterm in class: on Thursday October 29, 2009. The final exam is scheduled for Tuesday December 15, 2009 between 2:15pm-4:45pm. The place of the final exam will be announced on this web site towards the end of the semester.
Make certain that you will be available at these times, as there will be no scheduled make-ups for these tests.
Please note that makeup exams are only given if a student misses an exam for unforseeable circumstances beyond the student's control. In particular, schedule conflicts are not an acceptable reason for missing an exam.
There is a midterm exam during our usual class time and in our usual class room on Thursday October 29. The exam will cover the material of sections 1.1-1.6 and of 2.1-2.6 in our text book. A practice midterm can be found at practicemidterm
The average class grade on the midterm was 84%. Your midterm grade is recorded as a percentage grade. However, here is a rough translation of your percentage grade into a letter grade: A or A->89; B+,B or B->79; C+or C>69. The solutions to the midterm can be found at solutions to the midterm problems . The midterms will be handed back to students during their recitation this week (the week of 11/2-11/6).
The final exam will cover material from sections 2.5,2.6,3.1-3.3,9.1,9.2,9.5. It will take place in room 145 of Old Engineering at 2:15pm-4:45pm on December 15, 2009.
A practice final can be found at practice final exam
A very useful resource is the Math Learning Center (MLC) located in room S240-A of the mathematics building basement. The Math Learning Center is open M,Tu,Wed from 10:00am to 9:00pm, on Thur from 10:00am to 6:00pm, and on Fri from 10:00am to 2:00pm.
Another useful resource are your teacher and grader, whose office hours are listed above.
Students who require assistance during emergency evacuation are encouraged to discuss their needs with their professors and DSS. For procedures and information go to the following website: http://www.sunysb.edu/ehs/fire/disabilities.shtml
