Research Abstract |
I defined a matrix by using warping degrees which represents an oriented knot diagram on the sphere uniquely up to mirror image. This matrix is stronger than the warping polynomial which was also defined via warping degrees. I studied the reductivity of spherical curves and found that every spherical curve has the reductivity four or less.
