Will give a Topology Seminar entitled:
Ribbon knots and coloring surfaces in the four-ball
Abstract: When does a Fox p-colored knot in S^3 bound a Fox p-colored surface in B^4? I'll answer (a considerably more general version of ) this question and explain how it arises in the study of the slice-ribbon problem, via a ribbon obstruction obtained from the \Xi_p invariant of colored knots.
