Title |
Tangled diagrams and beyond |
Abstract |
In this talk we develop the notion of generalized vacillating tableaux from molecular contact structures. We prove a bijection between tangled diagrams (tangles) and vacillating tableaux, allowing for exact and asymptotic enumeration. We show how tangles connect the concepts of partitions and enhanced partitions, which are shown to be in bijection with a specific subclass of tangles. We then show how tangles embed in a generalization of the Brauer algebra and analyze the structure of the latter. |
