  • Gauss diagrams, unknotting numbers and trivializing numbers of spatial graphs 
    Kaur, K.; Kamada, S.; Kawauchi, A.; Prabhakar, M. (2021-10-07)
    In this paper we introduce Gauss diagrams and four kinds of unknotting numbers of a spatial graph. R. Hanaki introduced the notion of pseudo diagrams and the trivializing numbers of knots, links and spatial graphs whose ...
  • 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 ...
