On the Maximal Containments of Lower Central Series Ideals
arXiv:1509.08030
Abstract
We begin a discussion about the maximal containments of lower central series ideals: ideals generated by products of two-sided ideals of the lower central series of the free associative algebra on generators. We introduce two new ideas to the topic, the PBW grading and the pigeonhole principle, that help us give a complete classification of the containments for and obtain partial results in the general case.
