Abstract:

We prove that any non-hyperbolic genus one knot except the trefoil does not have a minimal canonical Seifert surface and that there are only polynomially many in the crossing number positive knots of given genus or given unknotting number.

Keywords:Positive knots   Seifert surfaces   Gauss{} diagrams   genus   unknotting number   alternating knots   Vassiliev invariants
