Abstract:

We show that if ${k_1}$ and ${k_2}$ are nonfibered knots, then the composite knot $K = {k_1}\# {k_2}$ has an infinite collection of minimal spanning surfaces, no two of which are isotopic by an isotopy which leaves the knot K fixed. This result is then applied to show that whether or not a knot has a unique minimal spanning surface can depend on what definition of spanning surface equivalence is used.
