Derivatives of Knots and Second-order Signatures
Tim Cochran, Shelly Harvey, Constance Leidy
We define a set of "second-order" L^(2)-signature invariants for any algebraically slice knot. These obstruct a knot's being a slice knot and generalize Casson-Gordon invariants, w…

Link concordance and generalized doubling operators
Tim Cochran, Shelly Harvey, Constance Leidy
We introduce a technique for showing classical knots and links are not slice. As one application we show that the iterated Bing doubles of many algebraically slice knots are not to…
