  • ARC shift number and region arc shift number for virtual knots 
    Gill, A.; Kaur, K.; Madeti, P. (2021-08-30)
    In this paper, we formulate a new local move on virtual knot diagram, called arc shift move. Further, we extend it to another local move called region arc shift defined on a region of a virtual knot diagram. We establish ...
  • 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 ...
