| Title: | Counting and cyclic symmetry |
| Abstract: | Part of combinatorics looks for nice formulas to count various objects. Sometimes these formulas hide an added surprise: when we introduce a variable to turn them into a polynomial, they count the objects with cyclic symmetry, after plugging in a complex root-of-unity for the variable! We will illustrate this with some of our favorite examples, including some that we still find mysterious. |
