Secant-quandle: an invariant of braids and knots

Liu Yangzhou

Abstract: We construct a novel invariant of braids and knots, secant-quandle (SQ),with generic secants serving as generators and generic horizontal trisecants serving as relations, i.e., SQ=Γ⟨S_M | S_T,E_M⟩, where M is a braid or link.
