Real expressive curves form a special class of real plane affine curves. This class of curves shares a number of interesting topological properties with morsifications of singularities of real plane curves. In particular, the link at infinity of a real expressive curve is isotopic to the link of its divide (in the sense of A’Campo). We discuss this result as well as related (conjectural) claims about the monodromy at infinity of real expressive curves.
