Math 502: Combinatorics II
This is the second semester of an introductory graduate-level course on combinatorics. We will be covering symmetric function theory, Young tableaux, counting with group actions, designs, matroids, finite geometries, and not-so-finite geometries.
Syllabus
For more details, see the Course Syllabus.
Resources
Recommended (but optional) books are listed in the Syllabus above.
These are the lecture notes from last year; major changes will be updated here as the course progresses.

Crash course on representation theory
Characters and the Murnaghan-Nakayama rule

Office hours
My office is Weber 125, near the west door of the tea room. Come find me:
- Wednesday 10 am and 12 noon, before and after class
- By appointment (Email me at Maria [dot] Gillespie [at] colostate [dot] edu)
- Feel free to knock on my office door for quick questions!
Homework
Homework assignments are starting out as the same as last year’s homeworks; I may add new problems to the ends of the homeworks based on what we cover in class. As usual you may choose a subset of the problems to hand in that adds up to 10 points.
Final Projects
The final projects written by the students will, with their permission, be posted here at the end of term.
Here is an Overleaf template to get you started with the format:
