Classical link invariants from the framizations of the Iwahori-Hecke algebra and the Temperley-Lieb algebra of type $A$

Abstract

In this paper we first present the construction of the new 2-variable classical link invariants arising from the Yokonuma-Hecke algebras ${\mathrm{Y}}_{d,n}(q)$, which are not topologically equivalent to the Homflypt polynomial. We then present the algebra ${\mathrm{FTL}}_{d,n}(q)$ which is the appropriate Temperley-Lieb analogue of ${\mathrm{Y}}_{d,n}(q)$, as well as the related 1-variable classical link invariants, which in turn are not topologically equivalent to the Jones polynomial. Finally, we present the algebra of braids and ties which is related to the Yokonuma-Hecke algebra, and also its quotient, the partition Temperley-Lieb algebra ${\mathrm{PTL}}_n(q)$ and we prove an isomorphism of this algebra with a subalgebra of ${\mathrm{FTL}}_{d,n}(q)$.
