The main goal of this course is to introduce you to some of some topics in algebraic combinatorics.

"Mathematics is not for spectators; in order to gain in understanding, confidence, and enthusiasm one has to participate." M.A. Armstrong


No Text Required

Of course, I invite you to visit the mathematics library (located in the second floor of Bradley Hall) and become acquainted with as many combinatorics books as you wish.

Scheduled Lectures


Professor Rosa Orellana

I encourage you to come to my office to discuss homework problems (yes, you can come before the homework is due), things that you don't understand in the course, opportunities for an REU (Research Experience for undergraduates) or if you are wondering what course to take next and need a little guidance.


There will be a take-home midterm and a final.


The project consists of reading an article from the "Algebraic Combinatorics Journal". This journal is available in the library. Please read and submit a summary. We might schedule a small 10 minute oral presentation. Choose anything that looks interesting to you.

Homework Policy and Guidelines

Homework will be assigned at the end of each period and will be due by the next period, unless otherwise indicated.


The course grade will be based upon the scores on the homework, two exams, participation (this means attending class and office hours as well as asking and responding to questions), the project and the final exam.

Exams 20%
Homework 20%
Project 20%
Participation 10%
Final Exam 30%

The Honor Principle

On Exams: You should work the problems on your own.

On Homework: Collaboration is permitted and encouraged, but NO COPYING . In other words, you should feel free to talk to other students while you are in the process of thinking about a problem. However, when it comes time to write up your solutions, you should do this by yourself without outside assistance.


Students with disabilities who will be taking this course and may need disability-related classroom accommodations are encouraged to make an appointment to see their instructor as soon as possible, certainly within the first two weeks of the course. Also, they should stop by the Academic Skills Center in Collis Center to register for support services.
