Disoriented homology and double branched covers
Brendan Owens, Sašo Strle
This paper provides a convenient and practical method to compute the homology and intersection pairing of a branched double cover of the 4-ball. To projections of links in the 3-ba…
Immersed disks, slicing numbers and concordance unknotting numbers
Brendan Owens, Saso Strle
We study three knot invariants related to smoothly immersed disks in the four-ball. These are the four-ball crossing number, which is the minimal number of normal double points of…
Non-orientable surfaces in homology cobordisms
Ira M. Gessel, Adam Simon Levine, Daniel Ruberman +1
We investigate constraints on embeddings of a non-orientable surface in a -manifold with the homology of , where is a rational homology -sphere. The constrain…
Dehn surgeries and negative-definite four-manifolds
Brendan Owens, Saso Strle
Given a knot K in the three-sphere, we address the question: which Dehn surgeries on K bound negative-definite four-manifolds? We show that the answer depends on a number m(K), whi…
Concordance properties of parallel links
Daniel Ruberman, Saso Strle
We investigate the concordance properties of `parallel links' P(K), given by the (2,0) cable of a knot K. We focus on the question: if P(K) is concordant to a split link, is K nece…
Smooth concordance of links topologically concordant to the Hopf link
Jae Choon Cha, Taehee Kim, Daniel Ruberman +1
It was shown by Jim Davis that a 2-component link with Alexander polynomial one is topologically concordant to the Hopf link. In this paper, we show that there is a 2-component lin…
