Topology of Maximally Writhed Real Algebraic Knots

  • G. B. Mikhalkin
  • S. Yu. Orevkov


Oleg Viro introduced an invariant of rigid isotopy for real algebraic knots in ℝℙ3 which can be viewed as a first order Vassiliev invariant. In this paper we look at real algebraic knots of degree d with the maximal possible value of this invariant. We show that for a given d all such knots are topologically isotopic and explicitly identify their knot type.
