A counterexample to Batson's conjecture
Published 31 May 2019 in math.GT | (1906.00799v1)
Abstract: We show that the torus knot bounds a smooth M\"obius band in the $4$-ball, giving a counterexample to Batson's non-orientable analogue of Milnor's conjecture on the smooth slice genera of torus knots.
