  • 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 ...
  • Region unknotting number of 2-bridge knots 
    Siwach, V.; Madeti, P. (2016-11-19)
    In this paper, we discuss the region unknotting number of different classes of 2-bridge knots. In particular, we provide region unknotting number for the classes of 2-bridge knots whose Conway notation is C(m, n), C(m, ...
  • 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 sequence for torus knots 
    Siwach, V.; Madeti, P. (2016-08-23)
    In this paper, the authors give an unknotting sequence for torus knots and also determine the unknotting numbers of View the MathML source, View the MathML source, View the MathML source, View the MathML source and some ...
  • Variation in Writhes of Virtual Knots under a local move 
    Gill, A.; Madeti, P. (2022-06-22)
    n-writhes denoted by Jn(K) are virtual knot invariants for n ≠ 0 and are closely associated with coefficients of some polynomial invariants of virtual knots. In this work, we investigate the variations of Jn(K) under arc ...
