  • An unknotting index for virtual knots 
    Kaur, K.; Kamada, S.; Kawauchi, A.; Madeti, P. (2021-08-09)
    In this paper we introduce the notion of an unknotting index for virtual knots. We give some examples of computation by using writhe invariants, and discuss a relationship between the unknotting index and the virtual knot ...
  • An unknotting index for virtual links 
    Kaur, K.; Prabhakar, M.; Vesnin, A. (2019-08-22)
    Given a virtual link diagram D, we define its unknotting index U(D)to be minimum among (m, n)tuples, where mstands for the number of crossings virtualized and nstands for the number of classical crossing changes, to obtain ...
