Ozsváth–Szabó and Rasmussen invariants of doubled knots
Let be any integer-valued additive knot invariant that bounds the smooth 4-genus of a knot K , j .K/j Ä g 4 .K/, and determines the 4-ball genus of positive torus knots, .T p;q / D .p 1/.q 1/=2.Either of the knot concordance invariants of Ozsváth-Szabó or Rasmussen, suitably normalized, …
