Abstract:
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, 2, m), C(m, 2, m ± 1) and C(2, m, 2, n). By generalizing, we also
provide a sharp upper bound for all the remaining classes of 2-bridge knots.
