The homology of a Temperley-Lieb algebra on an odd number of strands (2202.08799v2)
Published 17 Feb 2022 in math.AT
Abstract: We show that the homology of any Temperley-Lieb algebra $\mathcal{TL}_n(a)$ on an odd number of strands vanishes in positive degrees. This improves a result obtained by Boyd-Hepworth. In addition we present alternative arguments for the following two vanishing results of Boyd-Hepworth. (1) The stable homology of Temperley-Lieb algebras is trivial. (2) If the parameter $a \in R$ is a unit, then the homology of any Temperley-Lieb algebra is concentrated in degree zero.
