Enumerating (multiplex) juggling sequences
Abstract
Description
We consider the problem of enumerating periodic $σ$-juggling sequences of length $n$ for multiplex juggling, where $σ$ is the initial state (or {\em landing schedule}) of the balls. We first show that this problem is equivalent to choosing 1's in a specified matrix to guarantee certain column and row sums, and then using this matrix, derive a recursion. This work is a generalization of earlier work of Fan Chung and Ron Graham.
