A note on the unknotting number and the region unknotting number of weaving knots

Abstract

A weaving knot is an alternating knot whose minimal diagram is a closed braid of a lattice-like pattern. In this paper, upper bounds of the unknotting number and the region unknotting number for some families of weaving knots are given by diagrammatical and combinatorial examination of the warping degree of weaving knot diagrams.
