A slicing obstruction from the 10/8 theorem Donald, Andrew


A smooth knot slicing obstruction can be derived from Furuta's 10/8 theorem using 0-surgery on knots. I will show that this detects torsion elements in the concordance group and can be used to find topologically slice knots which are not smoothly slice. This is joint with F. Vafaee.
