Abstract
We investigate the properties of knots in which bound punctured Klein bottles, such that a pushoff of the knot has zero linking number with the knot, ie has zero framing. This is motivated by the many results in the literature regarding slice knots of genus one, for example, the existence of homologically essential zero self-linking simple closed curves on genus one Seifert surfaces for algebraically slice knots. Given a knot bounding a punctured Klein bottle with zero framing, we show that , the core of the orientation preserving band in any disk–band form of , has zero self-linking. We prove that such a is slice in a –homology if and only if is as well, a stronger result than what is currently known for genus one slice knots. As an application, we prove that given knots and and any odd integer , the –cables of and are –concordant if and only if and are –concordant. In particular, if the –cable of a knot is slice, is slice in a –homology ball.
