Topology of maximally writhed real algebraic knots

Abstract

Oleg Viro introduced an invariant of rigid isotopy for real algebraic knots in RP3RP^3 which can be viewed as a first order Vassiliev invariant. In this paper we look at real algebraic knots of degree dd with the maximal possible value of this invariant. We show that for a given dd all such knots are topologically isotopic and explicitly identify their knot type.
