p-adic framed braids

Abstract

In this paper we define the $p$-adic framed braid group ${\mathcal{F}}_{\infty ,n}$, arising as the inverse limit of the modular framed braids and we give topological generators for ${\mathcal{F}}_{\infty ,n}$. We also give geometric interpretations for the $p$-adic framed braids. We then construct a $p$-adic Yokonuma-Hecke algebra ${\mathrm{Y}}_{\infty ,n}(u)$ as the inverse limit of a family of classical Yokonuma-Hecke algebras. These are quotients of the modular framed braid groups over a quadratic relation. We also give topological generators for ${\mathrm{Y}}_{\infty ,n}(u)$. Finally, we construct on this new algebra a linear trace that supports the Markov property.
