The Refined Lecture Hall Theorem via Abacus Diagrams
arXiv:1211.3702
Abstract
Bousquet-Mélou & Eriksson's lecture hall theorem generalizes Euler's celebrated distinct-odd partition theorem. We present an elementary and transparent proof of a refined version of the lecture hall theorem using a simple bijection involving abacus diagrams.
