Abstract

Let β:=σ₁σ₂⁻¹ be a braid in B₃, where B₃ is the braid group on 3 strings and σ₁, σ₂ are the standard Artin generators. We use Gauss diagram formulas to show that for each natural number n not divisible by 3 the knot which is represented by the closure of the braid βⁿ is algebraically slice if and only if n is odd. As a consequence, we deduce some properties of Lucas numbers.
