Abstract

We formulate integrable flows related to the KdV hierarchy on null curves in the anti-de Sitter 3-space (AdS{\rm AdS}). Exploiting the specific properties of the geometry of AdS{\rm AdS}, we analyze their interrelationships with Pinkall flows in centro-affine geometry. We show that closed stationary solutions of the lower order flow can be explicitly found in terms of periodic solutions of a Lam\'e equation. In addition, we study the evolution of non-stationary curves arising from a 3-parameter family of periodic solutions of the KdV equation.
