Abstract

The 3-dimensional clasp number cl(K)cl(K) of a knot KK is the minimum number of clasp singularities of clasp disk, a singular immersed disk bounding KK whose singular set consists of only clasp singularities. We give a classification of clasp number two, genus two fibered knots under the assumption that they admit a clasp disk of certain type which we call of type II.
