On the detection of knots by their traces in high dimensions

Valentina Bais, Alessio Di Prisa, Daniel Hartman +8

For every $n \geq 4$ , we demonstrate the existence of non-isotopic, smooth $(n - 2)$ -knots in $S^{n}$ with diffeomorphic traces. We give two proofs: the first by generalising the RBG l…

Every negative amphichiral knot is rationally slice

Alessio Di Prisa, Jaewon Lee, Oğuz Şavk

In 2009, Kawauchi proved that every strongly negative amphichiral knot is rationally slice. However, as shown by Hartley in 1980, there are examples of negative amphichiral knots t…
